Vertiv 14678 Metered Vertical Rack PDU 20A 120V 20-Outlet
Overview
The Vertiv NSVBA200-102S20TL (part number 14678) is a metered vertical rack power distribution unit designed for high-density IT environments where catching an impending overload before it becomes a downtime event is worth more than the cost of the entire unit. At 66 inches tall and just 1.61 inches square, it mounts flush inside a standard cabinet without consuming a single rack unit — distributing 20A of 120V power across 20 individually spaced NEMA 5-20R outlets. If you manage mixed server and networking gear in a shared cabinet and have ever had to guess how close you are to tripping a breaker during a live migration, this is the unit to look at.

Key Features
- Local Digital RMS Current Meter (±2% Accuracy): Real-time current draw is readable directly from the LED display on the unit — no network connection, no software, no SNMP walk required. When you are physically moving equipment in a live rack, that local readout is the fastest way to confirm you haven't pushed the circuit past safe operating range. The ±2% accuracy at full-scale 60Hz sine wave is tight enough to trust for capacity planning, not just ballpark awareness.
- 20A / 1.9kW Load Capacity at 120V: Sized for a standard 20A branch circuit. The 1.9kW continuous load ceiling (keeping you under the NEC 80% rule on a 20A circuit) gives you practical headroom for a populated 1U/2U server mix. Going over that in a single cabinet typically means it's time to add a second circuit, not a higher-amperage PDU on the same feed.
- 20x NEMA 5-20R Outlets at 2.8-Inch Center Spacing: Twenty outlets is enough to cover a densely loaded 42U cabinet without daisy-chaining or using local power strips. The 2.8-inch center-to-center receptacle spacing keeps standard server power supplies and rack-mount UPS connectors from crowding each other — a real-world detail that matters when you are wiring a full cabinet and every inch counts.
- NEMA L5-20P Twistlock Input Plug with 10-Foot Power Cord (12/3 AWG): The L5-20P twistlock plug locks onto the wall PDU or UPS output — it will not vibrate loose in a shared facility with floor-mounted UPS systems or under-floor cabling. The 10-foot, 12/3 AWG cord is appropriately gauged for a 20A circuit and gives enough reach to get from a floor-mounted UPS or raised-floor outlet to the top of a standard cabinet without extension hardware.
- 20A Thermal Breaker Over-Current Protection: A thermal breaker trips on sustained overload and resets manually — it does not sacrifice itself like a fuse. For a data center environment where resetting a tripped breaker at 2 a.m. is vastly preferable to sourcing a replacement fuse, that distinction matters. The single breaker covers all 20 outlets simultaneously, which is standard for a unit at this price tier.
- 66.25-Inch Vertical Form Factor — Zero Rack Unit Consumption: The vertical mount clips to the inside rail of a standard 42U or 45U open-frame rack or enclosed cabinet. You get 20 outlets and a live metering display without sacrificing a single rack unit. Plastic mounting clips (one bottom, two top) are included and tool-optional on most standard rails.
- TAA Compliant, Buy American Act COTS Compliant, Made in USA: For federal, state, or municipal contracts requiring TAA or Buy American Act compliance, this unit ships with documentation. RoHS compliance and UL/c-UL Listing (60950) cover standard commercial and light-industrial deployments in North America and Canada.
- Continuous Operating Range 10–45°C (50–113°F): Covers typical data center and server-room environments. It will not perform in uncontrolled outdoor enclosures or in ambient temps above 113°F — plan accordingly if you are deploying in a non-conditioned telecom hut or industrial edge location.
Integration and Compatibility
The NSVBA200-102S20TL is a metered standard (not networked) unit — it provides local LED current metering only, with no SNMP, Modbus, or remote monitoring capability. If your deployment requires per-outlet switching, remote monitoring via a managed network switch or DCIM platform, or environmental sensor inputs, you will need to step up to a Vertiv networked or switched PDU variant. This unit plugs into any 20A NEMA L5-20P receptacle — typical sources include rack-mounted UPS systems, in-row PDUs, or dedicated 20A branch circuits at the floor or wall. Review your rack power distribution options to confirm circuit availability before ordering. The 20 NEMA 5-20R outlets accept standard 5-15P plugs as well, making it compatible with virtually all 1U and 2U server power supplies, KVM units, and patch panel power injectors found in mixed-vendor enterprise environments.
Frequently Asked Questions
Q: Does the Vertiv 14678 support remote monitoring or SNMP?
A: No. The 14678 (NSVBA200-102S20TL) is a metered standard unit with local LED current monitoring only. It does not include a network card, SNMP support, or remote access. For remote monitoring capability, Vertiv offers networked PDU variants in the same PowerIT rPDU family.
Q: What plug type does the 14678 use, and how long is the power cord?
A: The 14678 uses a NEMA L5-20P twistlock input plug on a 10-foot, 12/3 AWG power cord. This connects to any 20A NEMA L5-20P receptacle — common on rack-mount UPS units and dedicated 20A branch circuit outlets.
Q: What is the warranty on the Vertiv 14678?
A: The 14678 carries a 5-year limited manufacturer warranty, as documented in Vertiv's official product specification sheet.
Q: Is the Vertiv 14678 TAA compliant?
A: Yes. The 14678 is manufactured in the USA and is TAA Compliant and Buy American Act COTS Compliant, making it eligible for federal and government procurement contracts requiring domestic sourcing.
Q: Can the NEMA 5-20R outlets on the 14678 accept standard 5-15P plugs?
A: Yes. NEMA 5-20R receptacles are backward compatible with 5-15P plugs, so standard server power supplies and rack equipment with 15A plugs will connect without adapters.
Q: How does the 14678 mount in a rack cabinet?
A: The 14678 mounts vertically inside a standard rack or cabinet using the included plastic mounting clips — one at the bottom and two at the top. It does not consume any rack units (0U), leaving all usable rack space available for active equipment.
The Vertiv 14678 is the unit I reach for when a customer needs local current metering in a 20A cabinet but their DCIM budget is zero — the onboard digital RMS meter reads ±2% accuracy at full-scale 60Hz, which is more than adequate for verifying you're under the 16A NEC continuous load ceiling on a 20A circuit without pulling out a clamp meter every time you add a server.
Technical Highlights:
- Digital RMS Current Meter ±2%: Accurate enough to use as your primary capacity-planning reference for a 20A circuit — you don't need a network card to know you're at 14A and have 2A of safe headroom left before touching that 80% ceiling.
- 20x NEMA 5-20R at 2.8-inch centers: Twenty outlets across a 66.25-inch span means roughly one outlet every 3.3 inches — tight enough to fill a 42U cabinet but spaced to avoid the plug-stacking problem you get on cheaper units with 2-inch spacing and bulky server PSU connectors.
- L5-20P Twistlock on 12/3 AWG, 10-foot cord: The twistlock matters more than people think. In a colocation cage or shared data center floor where a stray foot catches a power cord, a locking plug is the only thing standing between you and an unplanned shutdown. The 12/3 gauge is correctly rated for sustained 20A draw without derating concerns.
Deployment Considerations:
- This is a local-monitoring-only unit — if your facility management team needs per-outlet current trending, environmental sensors, or outlet-level remote switching, you need a networked PDU. Don't order the 14678 expecting to retrofit a network card later; the metered standard platform doesn't support that upgrade path.
- Operating ceiling is 45°C (113°F) — fine for a conditioned server room, but verify ambient temps if you're deploying into a telecom hut, edge cabinet, or non-climate-controlled facility before committing to this unit.
Best fit for SMB or enterprise branch IT closets, colocation cages, and government deployments (TAA/Buy American compliance is built in) where a live current readout on the cabinet face is the primary requirement and remote monitoring will be handled upstream by the building's UPS or PDU at the panel level.
