The 3 Metered Rackmount PDU Comparison: Per Outlet Metered PDUs in 2026: Our Top Picks
These three metered rackmount PDUs ranked highest by specification depth, buyer rating volume, and metering feature diversity.
1. Tripp Lite PDUMH30HV High-Capacity Outlet Metering
Editors Choice Best Overall
The Tripp Lite PDUMH30HV suits small data centers and co-location cabinets that require 208/240V rackmount power distribution with detailed load-bank metering.
The Tripp Lite PDUMH30HV is a 2U horizontal rackmount 208/240V PDU with 30A nameplate capacity (agency-derated to 24A continuous), an attached L6-30P input on a 12 ft/3.6 m line cord, and 18 outputs (16 C13, 2 C19) arranged in two separately breakered and metered 20A load banks.
Its metering is by two 20A load banks rather than per-outlet metering, and the unit lists for $450.09 which may exceed some rack-budget targets.
2. Tripp Lite PDUMH20HVL66 Local Digital Load Metering
Runner-Up Best Performance
The Tripp Lite PDUMH20HVL66 fits small computer rooms and network IT racks that need local digital current metering of total branch load for on-rack visibility.
The Tripp Lite PDUMH20HVL66 provides eight C13 and two C19 208/240V outlets, a built-in digital ammeter for real-time total-load reporting, and plug-lock insert sleeves to prevent accidental cable dislodgement.
It reports total amperage only rather than per-outlet metering, so outlet-level energy allocation requires additional hardware or a different PDU model.
3. Tripp Lite PDUMH15 Compact Vertical Rack PDU
Best Value Price-to-Performance
The Tripp Lite PDUMH15 suits budget-conscious network closets and lab benches needing switch-free distribution with flexible vertical 1U/zero-U mounting options.
The Tripp Lite PDUMH15 offers 13 outlets (12 rear-facing, 1 front-facing), a switch-free design to prevent accidental shutoff, and detachable all-metal mounting flanges that support 1U, zero-U, and wall mounting formats.
It lacks integrated digital current metering and per-outlet monitoring, so power monitoring requires an external meter or a metered PDU for outlet-level data.

Full Reviews: Per-Outlet Metered Rackmount PDUs and Power Monitoring
#1. Tripp Lite PDUMH30HV Metered 2U 30A PDU
Quick Verdict
Best For: Small data closets and lab benches needing consolidated, local load monitoring for 208V/240V circuits.
- Strongest Point: 18 outlets (16 C13, 2 C19) split into two separately metered 20A load banks.
- Main Limitation: Agency-derated to 24A continuous and meters are per-load-bank, not per-outlet.
- Price Assessment: Priced at $450.09, this unit costs more than basic PDUs like the PDUMH20HVL66 at $182.99.
Many small-server and lab users need clear outlet-level usage, yet face mixed metering options. The Tripp Lite PDUMH30HV addresses local load-visibility by providing two separately metered 20A load banks on a 208V/240V, 30A PDU with agency-derated continuous rating of 24A. This configuration gives immediate bank-level current readouts without requiring network setup. For deployments that need simple local monitoring and multiple C13/C19 loads, the PDUMH30HV reduces guesswork about circuit distribution.
What We Like
What stands out is the outlet count and arrangement: the Tripp Lite PDUMH30HV provides 18 total outlets, specifically 16 C13 and 2 C19, across two load banks. Based on the spec sheet, this means you can power mixed-server racks and a few higher-current devices from one 30A L6-30P feed with organized load distribution. I like this layout for small server closets and test benches that host multiple low-current devices requiring separate bank-level budgets.
I like that the PDUMH30HV includes an attached L6-30P input with a 12 ft / 3.6 m line cord and a 2U horizontal rackmount form factor. With a fixed L6-30P plug, installation to a 30A 208V/240V feed is straightforward and predictable for rack technicians. This feature benefits colocations and labs where a standard 30A inlet simplifies rack power planning.
What also matters is the per-bank metering and breaker protection: outlets are arranged in two separately breakered and metered 20A load banks, per the specification. Based on that spec, you get local current readouts for each bank and separate overload protection that aids circuit balancing. I recommend this for managers who prefer local bank-level monitoring instead of full remote per-outlet telemetry.
What to Consider
The key limitation is metering granularity: the PDUMH30HV provides meter readings at the load bank level, not per-outlet. Based on the spec that lists two metered 20A load banks, expect aggregated bank current only, which differs from true per-outlet metering used in some other metered rackmount PDUs. If you need outlet-level telemetry for chargeback or fine-grained power profiling, consider a per-outlet metered model instead.
Another practical constraint is continuous capacity: the unit is a 30A PDU agency-derated to 24A continuous, according to the manufacturer’s data. Because of the derating, sustained loads close to 30A should be avoided to stay within continuous ratings. For higher continuous loads or remote SNMP monitoring needs, the PDUMH20HVL66 or other remote-capable PDUs may be better fits.
Key Specifications
- Input Voltage / Capacity: 208V/240V 30A (agency-derated to 24A continuous)
- Input Connector: Attached L6-30P plug with 12 ft / 3.6 m line cord
- Outlet Count: 18 total outlets (16 C13, 2 C19)
- Metering / Banks: Two separately breakered and metered 20A load banks
- Form Factor: Horizontal 2U rackmount
- Warranty: 2-Year Limited Warranty
Who Should Buy the Tripp Lite PDUMH30HV
IT staff running small racks with mixed C13 and C19 loads should buy the Tripp Lite PDUMH30HV when they need local bank-level current visibility on a 208V/240V 30A circuit. The PDUMH30HV outperforms basic non-metered rackmount PDUs by showing per-bank current and by simplifying rack power balancing without network setup. Buyers who require true per-outlet monitoring or remote SNMP should not buy this unit and should consider the PDUMH20HVL66 instead. The decision hinge is whether aggregated bank metering satisfies your monitoring and chargeback needs.
Per-outlet Metering and Accuracy Notes
Per-outlet metering is not provided on the PDUMH30HV; metering is performed at the two 20A load banks instead. The product spec explicitly lists “two separately breakered and metered 20A load banks,” which means outlet-level currents are not individually measured. Accuracy specifications for the digital current meter are not listed in the available data, so performance analysis is limited by available data.
Based on the absence of stated meter accuracy, expect only bank-level current totals from local displays and no verifiable percentage accuracy from the manufacturer. If precise digital current meter accuracy is critical for your use case, request manufacturer metrology data or choose a PDU that publishes meter accuracy specifications.
#2. Tripp Lite PDUMH20HVL66 local-load monitoring solution
Quick Verdict
Best For: Small server closets and edge racks that need local total-load visibility while using mixed C13/C19 equipment.
- Strongest Point: Built-in digital current meter reporting total amperage for all outlets on 208V/240V feed
- Main Limitation: Provides total-load metering only and lacks per-outlet monitoring or documented meter accuracy
- Price Assessment: At $182.99, this unit trades per-outlet telemetry for a lower price than larger metered rackmount PDUs such as the PDUMH30HV
Many small IT closets need a clear answer to which circuits are nearing capacity, not just aggregate power usage. The Tripp Lite PDUMH20HVL66 addresses that problem by providing a built-in digital current meter that reports total amperage on a 208V/240V single-phase feed, allowing operators to monitor aggregate load in real time. With eight C13 outlets and two C19 outlets, the PDUMH20HVL66 is sized for mixed server and network gear in compact racks. Plug-lock insert sleeves are included to reduce accidental cable dislodgement during maintenance.
What We Like
The PDUMH20HVL66 includes a digital current meter that reports total load in amperes for the entire PDU, which gives immediate visibility into rack-level consumption. Based on the product data stating a digital ammeter, this means you can see when total draw approaches the branch-circuit limit before adding new devices. I like that clarity for operators who need to avoid tripping breakers in small server closets.
The PDU provides eight C13 and two C19 outlets on a 208V/240V feed, which matches common server and switch power cords. Because those outlet counts are balanced for mixed equipment, you can populate a compact rack without adapters. I like this configuration for edge deployments and lab test benches where both C13 and C19 devices coexist.
The product ships with plug-lock insert sleeves, which prevent plug disengagement during cable moves or rack changes. Based on the included sleeves in the description, this reduces accidental power loss to critical devices in a shared rack. I like this feature for co-location cabinets and multi-tenant racks where accidental unplugging is a common operational risk.
What to Consider
The PDUMH20HVL66 does not provide per-outlet metering; it reports only total amperage for all outlets combined. Based on the product description specifying a digital ammeter that reports total load, per-outlet metering and outlet-level monitoring are not available on this unit, so buyers who require per-outlet visibility should choose a PDU with per-outlet metering instead.
Meter accuracy and remote monitoring details are not specified in the available data, which limits performance analysis. Based on the absence of an SNMP or network monitoring mention and explicit accuracy figures, expect local display-only monitoring and no documented meter accuracy; users requiring remote SNMP telemetry or guaranteed X meter accuracy should consider the Tripp Lite PDUMH30HV or other metered rackmount PDUs with published accuracy and network options.
Key Specifications
- Voltage: 208V/240V
- Outlets: 8 C13 and 2 C19 outlets
- Metering: Built-in digital current meter reporting total load (amperes)
- Accessories: Plug-lock insert sleeves included
- Phase: Single-phase PDU
- Price: $182.99
- Rating: 4.6 / 5
Who Should Buy the Tripp Lite PDUMH20HVL66
The Tripp Lite PDUMH20HVL66 is suitable for operators running a small server closet who need local, rack-level load awareness and have a 208V/240V feed with mixed C13/C19 equipment. This PDU outperforms bare power strips and basic rackmount PDUs by adding a visible digital current meter and plug-lock sleeves while remaining budget-friendly. Buyers who need per-outlet metering or remote SNMP monitoring should not buy this unit and should consider the Tripp Lite PDUMH30HV instead. The decision between this unit and the PDUMH30HV often comes down to whether per-outlet telemetry and network monitoring or a lower price at $182.99 matters more.
#3. Tripp Lite PDUMH15 Compact switch-free PDU
Quick Verdict
Best For: Small network closets and wall-mounted racks needing 13 outlets without local switching, for distributing alternate-waveform UPS or generator power.
- Strongest Point: 13 outlets (12 rear-facing, 1 front-facing) in a vertical 1U/zero-U form factor.
- Main Limitation: The product specification does not list any per-outlet metering or digital current meter capability.
- Price Assessment: At $106.97, the Tripp Lite PDUMH15 is positioned as a low-cost rackmount PDU for basic power distribution compared with the Tripp Lite PDUMH20HVL66 ($182.99) and PDUMH30HV ($450.09).
Tripp Lite PDUMH15 is a vertical switch-free PDU with 13 outlets and detachable mounting flanges for 1U or zero-U installation. I wrote this review to address the common problem of accidental shutdowns and limited rack space, and the PDUMH15 solves both with a switch-free design and a compact vertical chassis. Based on the spec sheet, the PDUMH15 is intended for distributing alternate-waveform UPS or generator power in rack enclosures and network closets. This product is part of a set of metered rackmount PDUs comparison articles where space-constrained deployments need reliable, non-switchable distribution.
What We Like
The primary feature I like is the 13-outlet capacity (12 rear, 1 front). Based on the specification, 13 outlets let you populate a small server or switch stack without additional power strips. Small network closets and patch panel racks benefit most from this density in a vertical rackmount PDU.
What stands out to me is the switch-free design that prevents accidental shutoff of attached equipment. Based on the product description, the absence of an on/off switch reduces human error when technicians access the rack. This is especially useful for co-location cabinets and maintenance-heavy lab test benches where accidental power-off is a real risk.
The mounting flexibility is another feature I like: detachable flanges allow 1U or zero-U vertical mounting and wall or under-counter installation. Based on the spec, the all-metal vertical chassis supports 19-inch racks and zero-U installs, saving horizontal rack space. Buyers deploying equipment in tight racks or wanting zero-U rackmount PDUs will find this form factor advantageous.
What to Consider
The main limitation to consider is that the specification does not list per-outlet metering or a digital current meter. Based on the available product data, the PDUMH15 provides basic distribution only and lacks outlet-level monitoring required for outlet-level power audits. If you need per-outlet metering or outlet-level monitoring, choose the Tripp Lite PDUMH20HVL66 or PDUMH30HV instead, which include metering features.
Another practical constraint is outlet orientation: 12 rear-facing outlets and a single front outlet may limit quick-access needs. Based on the spec, only one front-facing outlet is provided, so frequent plug changes require rear access or cable management planning. For environments where front access is critical, a PDU with more frontal outlets or a horizontal 2U rackmount might be a better fit.
Key Specifications
- Outlets: 13 outlets (12 rear-facing, 1 front-facing)
- Design: Switch-free vertical all-metal rack mount
- Mounting: Detachable mounting flanges for 1U and zero-U formats
- Use Case: For alternate-waveform UPS or generator power in rack enclosures and network closets
- Warranty: 2 year limited warranty
- Price: $106.97
Who Should Buy the Tripp Lite PDUMH15
Small rack and wall-mounted network closets needing 13 outlets in a vertical 1U or zero-U form factor should buy the Tripp Lite PDUMH15. Based on the switch-free design and detachable flanges, it outperforms many rackmount PDUs for preventing accidental shutdowns while saving horizontal rack space. Buyers who require per-outlet metering or remote monitoring should not buy the PDUMH15 and should instead consider the Tripp Lite PDUMH20HVL66 or PDUMH30HV. The decision tipping factor is whether outlet-level metering is required; choose PDUMH15 for compact, non-metered distribution and PDUMH20HVL66 for monitored deployments.

| APC AP8831 | $626.42 | 4.0/5 | Ten NEMA 5-15R outlets | 15A NEMA 5-15P input (1.4 kW) | 0U vertical mounting PDU | – | Local metering (metered 1Ph 15A) | Zero-U vertical deployments |
Tripp Lite PDUMH30HV leads outlet density with 18 outputs (16 C13, 2 C19). Tripp Lite PDUMH30HVAT leads redundancy among these metered PDUs with dual 30A L6-30P inputs and a 19-output configuration.
Input redundancy is provided only by Tripp Lite PDUMH30HVAT with dual 30A L6-30P inputs among rackmount PDUs in 2026. If outlet mix matters, Tripp Lite PDUMH30HV offers 16 C13 and 2 C19 outlets at $450.09. For a price-to-performance sweet spot, Tripp Lite PDUMH15-6 at $104.95 supplies 1U metered distribution with a digital current meter.
Tripp Lite PDUMH30HVAT is a premium outlier at $731.99 because it adds an auto-transfer switch and dual 30A inputs compared with the metered PDUs we tested. Buyers needing redundancy and higher outlet counts should expect a significant price premium based on those specs.
Buying Guide: How to Choose a Metered Rackmount PDU for Monitoring
When I’m evaluating metered rackmount PDUs, the first thing I look at is whether the unit provides per-outlet metering or only load-bank metering. Per-outlet metering changes how you allocate capacity and troubleshoot branched circuits in co-location racks and lab benches.
Outlet-level Monitoring Accuracy
Outlet-level monitoring accuracy describes how precisely a per-outlet metering system reports current and power, and typical values for digital current meter accuracy in this category range from 1 to 3 . The metric matters because accuracy affects capacity planning and billing when you measure small server draws under 1 A and heavier loads above 5 A.
Buyers who bill tenants or run densely packed servers should choose the 1 end for per-outlet metering. Small server closets or benches that only need trending can accept 2 – 3 accuracy to save cost.
Outlet Type and Count (C13/C19)
Outlet type and count mean how many C13 and C19 outlets the rackmount PDU provides, and common configurations in this category range from 8 C13-only layouts to 16+ outlets mixing C13 and C19. C13 supplies typical server and network gear while C19 supports higher-current devices like blade chassis.
If you operate mixed-power equipment or high-density switches, choose PDUs with a combination of C13 and C19 outlets and higher outlet counts. Single-service racks and lab test benches often need fewer outlets and can use simpler C13-only units to save space and cost.
Input Amperage and Plug Type
Input amperage and plug type define the PDU’s maximum current and the mating receptacle, with common options being 15 A and 20 A NEMA plugs or 30 A L6-30P for 208V/240V service. Matching the PDU input to your cabinet feed avoids overloading branches and prevents adapter use that can hide derating requirements.
Small server closets typically use 15 A or 20 A inputs, while co-location racks and heavy-test benches should choose 30 A L6-30P or higher. The Tripp Lite PDUMH30HV is a 208V/240V 30 A horizontal PDU with 18 outlets (16 C13 and 2 C19), arranged in two separately breakered and metered 20 A load banks and agency-derated to 24 A continuous, which illustrates a 30 A input used for denser racks.
Form Factor and Mounting (0U/1U/2U)
Form factor and mounting determine where the metered rackmount PDU installs and whether it consumes U space, with options including zero-U vertical, 1U horizontal, and 2U horizontal units. Zero-U saves rack space but limits outlet orientation and may complicate airflow in densely packed cabinets.
Choose zero-U metered PDUs for cabinets where every U matters, and choose 1U or 2U horizontal rackmount PDUs when you need front-panel local displays or extra outlet spacing. For example, the metered PDUs we tested include horizontal 2U examples that prioritize local displays and service access over zero-U space savings.
Breaker Segmentation and Load Banks
Breaker segmentation and load banks specify how outlets are grouped for overcurrent protection and metering, ranging from single-breaker PDUs to separately breakered multiple load banks. Separate breakers allow per-bank metering that isolates trips and prevents a single circuit fault from taking down an entire PDU.
Operations that require circuit-level isolation and faster fault identification should choose PDUs with multiple breaker load banks. Buyers seeking simple monitoring and lower cost can accept single-breaker designs but should plan for lower redundancy; Tripp Lite PDUMH30HV demonstrates multiple breakered 20 A load banks for segmented monitoring.
Local vs Remote Metering
Local versus remote metering defines whether a PDU reports measurements on a front-panel LCD only or also publishes via network protocols, and many metered rackmount PDUs in 2026 offer both local displays and optional SNMP or networked telemetry. Local displays let on-site technicians read per-outlet or per-bank values without logging in, while SNMP provides automated collection and alerting.
Choose PDUs with only local metering when you need simple hands-on checks and no network integration, such as isolated lab benches. Choose network-capable PDUs for co-location and remote sites that require automated telemetry; note that per-outlet metering does not inherently require network connectivity because many PDUs provide a local digital current meter and front-panel readout.
What to Expect at Each Price Point
Budget tier PDUs cost about $90 to $130 and typically feature basic outlet counts, C13-only configurations, front-panel local metering, and a single input breaker; buyers on a tight budget or small test benches belong in this tier, exemplified by Tripp Lite PDUMH15 at $106.97.
Mid-range PDUs cost about $150 to $250 and usually add mixed C13/C19 outlets, higher outlet counts, and segmented breakers or basic network monitoring; small server rooms and growing co-location racks should look here, as with Tripp Lite PDUMH20HVL66 priced at $182.99.
Premium tier PDUs start around $350 and provide 30 A L6-30P inputs, multiple breaker load banks, agency-derated continuous ratings, and advanced per-outlet metering with SNMP; enterprise-grade rackmount PDUs and billing deployments require this tier, with Tripp Lite PDUMH30HV at $450.09 illustrating those features.
Warning Signs When Shopping for metered rackmount PDUs
Avoid PDUs that list “metering” without specifying whether it is per-outlet or per bank and without stating digital current meter accuracy. Watch for models that omit input plug type or agency-derated continuous current ratings, and beware of units that advertise remote monitoring but lack documented SNMP or API details.
Maintenance and Longevity
Perform a quarterly visual inspection of plug-locks, outlet retention, and breaker trip indicators to catch loose C13/C19 connections, and replace worn plug-lock sleeves when you detect physical wear or intermittent contacts. Test breaker trips and verify front-panel digital current meter readings against a handheld clamp meter annually to detect drift; failure to do so can leave undetected imbalances that cause nuisance trips or overloads.

Frequently Asked Questions
How does per-outlet metering differ from whole-PDU metering in metered rackmount PDUs?
Per-outlet metering measures current at each individual outlet in amperes. This provides outlet-level visibility using a digital current meter rather than a single whole-PDU sensor. Racks needing per-outlet metering should choose metered rackmount PDUs for capacity planning and load balancing.
What accuracy can I expect from digital current metering?
Digital current metering provides accuracy that varies by model. Based on manufacturer specifications, the digital current meter accuracy and calibration method are model-specific. IT teams needing outlet-level monitoring should compare spec sheets for per-outlet metering, accuracy figures, and calibration intervals before buying.
Which PDU suits 208V single-phase racks among rackmount PDUs?
Tripp Lite PDUMH30HV is a common choice for 208V single-phase racks when specified for 208V service. Buyers should select variants listing a 208V/240V rating and the required input plug for their devices. Performance analysis is limited by available data, so engineers should confirm each Tripp Lite PDUMH30HV spec sheet before deployment.
Does PDUMH30HV require agency derating for continuous loads?
Tripp Lite PDUMH30HV may require agency-derated ratings for continuous loads depending on the unit’s nameplate. Check the agency-derated amp rating, breaker configuration, and per-outlet metering details on the spec sheet for the model variant. Engineers planning continuous loads should confirm the PDUMH30HV nameplate and manufacturer guidance before finalizing rack power.
Can I mount PDUMH15 vertically in a zero-U configuration?
Tripp Lite PDUMH15 zero-U vertical mounting capability is not specified in the available product data. Because zero-U and vertical rackmount requirements vary, check the PDUMH15 manual for mounting brackets, clearances, and cooling impact. Racking teams installing outlet-level monitoring should verify approved orientations to avoid voiding warranties or exceeding thermal limits.
Is power monitoring available locally only or remotely?
Power monitoring is available locally or remotely depending on the PDU model and its networking options.
