Vertiv 11108 Metered Horizontal Rack PDU, 20A 208V 3.3kW

Overview

The Vertiv 11108 — model VHVRC120-102D20TL6 — is a 1U horizontal rack PDU built for 208V data center and server room environments where you need real-time power visibility without deploying a full network-managed unit. It delivers 20A at 208V (3.3kW load capacity) across 12 NEMA 6-20R receptacles, and every unit ships 100% factory-tested before leaving the line. If you're loading high-density servers, networking gear, or KVM switches into a standard 19-inch rack and you want instant overload awareness at the unit — not via a management console — this is the class of PDU to reach for.

Key Features

• Local RMS Scrolling Power Meter (±2% accuracy): The front-panel LED display scrolls real-time amps, volts, watts, and power factor. When you're hot-swapping a server at 2 a.m. or redistributing load across PDUs, you don't need to log into anything — the answer is right on the unit. The ±2% accuracy rating means the numbers you're reading are usable for capacity planning, not just rough guidance.
• 20A Double Pole Magnetic Breaker: The magnetic breaker trips faster than thermal breakers under hard fault conditions and resets cleanly without the wear-out failure mode of fuse-based protection. A double-pole configuration breaks both legs simultaneously on a 208V circuit — important for safe de-energization on two-phase power.
• 12 NEMA 6-20R Receptacles (2 face / 10 rear): The 2-front / 10-rear outlet split is practical — face outlets handle devices you're actively connecting and disconnecting (test equipment, temporary KVM access), while the 10 rear positions lock in your permanent cabinet loads. All 12 share a single 20A breaker, so plan your load distribution accordingly before you fill every slot.
• NEMA L6-20P Twistlock Input Plug, 10ft 12/3 Cable: The L6-20P twistlock plug is the standard connector for 208V 20A utility circuits in data centers and colocation environments. The 10-foot, 12 AWG cord gives you enough reach to route cleanly to overhead or floor-level PDPs without creating a cable management problem. 12 AWG wire is rated comfortably for 20A continuous draw.
• 200–240V Input Range, 50/60Hz: The wide voltage tolerance means this unit works across both 208V North American two-phase circuits and 220–240V single-phase international installations. Useful if you're standardizing PDU inventory across domestic and international sites, or if your facility voltage fluctuates above 208V nominal.
• TAA Compliant, Buy American Act COTS Compliant, Made in USA: TAA and BAA compliance are hard requirements for federal, DoD, and many state government procurement contracts. This unit ships from US manufacturing, which also shortens lead times and simplifies supply chain documentation for government projects.
• RoHS Compliant, UL & c-UL Listed 60950: UL 60950 listing covers IT equipment power distribution safety — not just general electrical. RoHS compliance matters for e-waste regulations in California and EU installations. Both certifications are standard requirements for enterprise and government data center acceptance testing.
• 1U Horizontal 19-inch Rackmount, Adjustable Brackets: The 1.72in × 17in × 6.50in chassis fits a standard 19-inch rack in 1U. Adjustable mount brackets let you position it in 2-post or 4-post racks without adapters. At 7 lbs shipped weight, two-person installation isn't required, but rack rail seating should be verified before you load all 12 outlets.
• 5-Year Limited Warranty: A 5-year warranty on a rack PDU is meaningful — these units typically stay in service for 7–10 years in production environments. The warranty duration aligns with typical server refresh cycles, so you're covered through the life of the gear you're powering.
• Operating Temperature 10–45°C (50–113°F): This covers the full range of standard data center operating conditions (ASHRAE A1/A2 classes). If you're running a hot-aisle/cold-aisle configuration with inlet temps near 40°C, you're still within spec — but leave margin between the PDU and heat-producing gear with poor airflow.

Integration and Compatibility

The 11108 is a metered standard unit — meaning it reads aggregate power at the unit level only, not per-outlet. If your environment requires per-outlet switching or per-outlet metering (useful for billing or granular load balancing), step up to a switched or outlet-metered Vertiv rPDU in the same PowerIT line. For environments where the aggregate view is sufficient — most single-tenant server rooms, remote offices with small cabs, and colocation cages where you own the whole PDU — the 11108 delivers the monitoring you need without paying for outlet-level intelligence you won't use.

The L6-20P input plug is compatible with standard 20A 208V circuit breakers found in most North American data center panel boards. Pair this with a rack enclosure rated for the PDU's 17-inch width and confirm your facility's circuit capacity before deploying — 3.3kW continuous at 80% NEC loading means your circuit breaker should be rated for at least 20A, which this PDU's input plug already matches.

For larger deployments requiring centralized monitoring, this unit can coexist in a rack alongside network-managed PDUs without conflict — it simply won't appear on your DCIM dashboard. If remote monitoring of individual rack power distribution circuits becomes a requirement post-deployment, swap to a networked variant in the Vertiv PowerIT family rather than retrofitting.

Frequently Asked Questions

Q: What is the maximum load capacity of the Vertiv 11108?

A: The 11108 supports a maximum load of 3.3kW at 208V with a 20A input current. All 12 NEMA 6-20R receptacles share a single 20A double pole magnetic breaker, so total connected load across all outlets must not exceed 20A (NEC 80% continuous load rule recommends staying under 16A continuous).

Q: Does the 11108 provide per-outlet metering or switching?

A: No. The 11108 is an aggregate-level metered unit — it monitors total amps, volts, watts, and power factor for the entire PDU via the local LED display. It does not offer per-outlet metering or remote outlet switching. If per-outlet visibility or control is required, a switched or outlet-metered Vertiv rPDU is the appropriate choice.

Q: Is the Vertiv 11108 TAA compliant?

A: Yes. The 11108 is TAA (Trade Agreements Act) compliant and Buy American Act COTS compliant, manufactured in the USA. This makes it eligible for federal, DoD, and many state/local government procurement contracts requiring domestic or TAA-approved country of origin.

Q: What warranty is included with the 11108?

A: Vertiv includes a 5-year limited warranty with the 11108.

Q: What input plug does the 11108 use, and how long is the power cord?

A: The 11108 uses a NEMA L6-20P twistlock plug on a 10-foot, 12/3 AWG power cord. This plug mates with standard 20A 208V twistlock receptacles commonly found in data center power panels and PDPs.

Q: Can the 11108 be monitored remotely over a network?

A: No. The 11108 is a local-display-only metered PDU — power data (A, V, W, PF) is shown on the unit's LED display but is not transmitted over a network. There is no Ethernet port or network management capability on this model. Remote monitoring requires a network-managed Vertiv rPDU variant.

James Everett

The Vertiv 11108 is one of those PDUs I recommend when teams ask for power visibility without the overhead of network management. The ±2% accuracy on the local RMS meter is the specification I keep coming back to — it's tight enough to use for capacity planning conversations, not just a ballpark check before you plug in the next server. If you're managing a high-density cabinet and you want to know whether you have 3A of headroom before hitting the breaker, that ±2% reading is trustworthy.

Technical Highlights:

• Aggregate Metering (A, V, W, PF): The scrolling LED display reads all four power parameters — current, voltage, wattage, and power factor. Power factor visibility matters in environments with switching power supplies, which can pull PF below 0.9 and inflate apparent load beyond what wattage alone would suggest.
• 20A Double Pole Magnetic Breaker: Magnetic breakers respond to fault current faster than thermal types and don't degrade with repeated trips the way thermal-magnetic breakers can. The double-pole design simultaneously opens both legs of the 208V circuit — correct behavior for two-phase power, which a single-pole breaker would not accomplish safely.
• 12/3 AWG, 10ft Cord with L6-20P Twistlock: 12 AWG wire at 20A gives you a safe continuous load margin. The L6-20P twistlock is the de facto standard for 208V 20A data center circuits — it won't accidentally disconnect under vibration or cable tension the way a straight-blade plug can.

Deployment Considerations:

• The 2-face / 10-rear outlet split is fixed — you can't relocate rear outlets to the front. Plan your cable management before you mount the unit, particularly if you have front-access equipment that needs direct outlet proximity.
• This is aggregate metering only: there is no per-outlet current reading. If a single device is drawing anomalous current, the unit won't isolate which receptacle is the source — you'd need a clamp meter or a stepped outlet-metered PDU for that level of diagnosis.

The 11108 is the right fit for government or defense-adjacent data rooms where TAA and Buy American compliance are non-negotiable procurement requirements, and where the operations team wants local power confirmation without adding a managed device to the network inventory. It's particularly well-suited for 4–8 rack deployments in remote or edge facilities where a full DCIM rollout isn't justified but load awareness at the rack still matters.
