Vertiv 12348 20A Vertical Rackmount Basic PDU
Overview
The Vertiv 12348 — model NSVB200-102S20TL — is a basic vertical rackmount power distribution unit designed to deliver reliable 20A/120V power across 20 NEMA 5-20R receptacles in a single rack column. At 66.25 inches long and just 1.61 inches square in cross-section, it mounts flush along the rear vertical rail without consuming a single rack unit of usable equipment space. Every unit ships 100% factory-tested. Manufactured in the USA, the 12348 is TAA Compliant and Buy American Act COTS Compliant — a prerequisite for federal, defense, and government-funded installations.

Key Features
- 20A Single-Circuit Capacity at 1.9kW: All 20 outlets share a single 20A thermal breaker, giving the full 1.9kW load budget to a single rack. That's enough headroom for dense 1U/2U server populations drawing 80–100W each without nuisance trips — thermal breakers respond to sustained overload rather than momentary inrush spikes.
- 20x NEMA 5-20R Receptacles at 2.8in Spacing: The 2.8-inch center-to-center outlet spacing accommodates standard IEC C13/C15 power cords without brick-on-brick conflicts. Twenty outlets per strip means fewer PDUs per rack compared to 8- or 12-outlet horizontal alternatives — relevant when you're budgeting rack real estate on vertical rack power distribution deployments.
- NEMA L5-20P Twistlock Input Plug: The L5-20P locking plug prevents accidental disconnection at the UPS or transfer switch output — a real risk in high-density rows where cable management gets crowded. The 10-foot 12/3 AWG power cord provides enough slack to reach most rear-mounted UPS bypass panels without extension hardware.
- Vertical 66in Form Factor — Zero Rack U Consumed: Installs via three plastic mounting clips (one bottom, two top) along the vertical rail. No dedicated rack unit required, so every U stays available for active equipment. Works with standard 2-post and 4-post open-frame racks as well as enclosed cabinets.
- Single Green Power-On LED Indicator: A single green LED confirms live input — no display, no network port, no firmware. That simplicity is a feature in air-gapped environments or deployments where managed PDU attack surface is a concern.
- TAA and Buy American Act COTS Compliant: Manufactured in the USA and certified under the Trade Agreements Act. Qualifies for GSA schedule procurement and federally funded projects without a waiver — skip the compliance review cycle that imported alternatives require. Pair this with a compliant rack and enclosure for a fully TAA-clean build.
- RoHS Compliant, UL and c-UL Listed: UL 60950 listing covers both US and Canadian markets. RoHS compliance supports sustainability procurement mandates in corporate and government environments.
- 5-Year Limited Warranty: Vertiv's standard five-year limited warranty on the 12348 is longer than the two- or three-year coverage common on competing basic PDUs — useful when budgeting total cost of ownership on 5–7-year rack refresh cycles. Review your UPS and power protection options to complete the power chain.
Integration and Compatibility
The NSVB200-102S20TL connects to any 20A NEMA L5-20 output on a UPS, automatic transfer switch, or wall circuit. NEMA 5-20R outlets accept standard NEMA 5-15P plugs as well as 5-20P plugs, so existing equipment with 15A cords connects without adapters. Operating range of 100–120V / 50–60Hz covers both 60Hz North American and 50Hz applications. No software, drivers, or network integration required — install and energize.
Frequently Asked Questions
Q: Is the Vertiv 12348 TAA compliant?
A: Yes. The 12348 (NSVB200-102S20TL) is manufactured in the USA and is both TAA Compliant and Buy American Act COTS Compliant, qualifying it for federal and government-funded procurement.
Q: What plug type does the 12348 use for its input connection?
A: The 12348 uses a NEMA L5-20P twistlock plug on a 10-foot, 12/3 AWG power cord. It connects to any 20A NEMA L5-20 receptacle on a UPS or transfer switch output.
Q: Can I connect equipment with standard 15A NEMA 5-15P plugs to the 12348?
A: Yes. NEMA 5-20R receptacles accept both NEMA 5-20P and NEMA 5-15P plugs, so existing servers and network gear with standard 15A cords connect directly without adapters.
Q: What is the warranty on the Vertiv 12348?
A: Vertiv covers the 12348 with a 5-year limited warranty — longer than the 2–3 year coverage typical of competing basic PDUs.
Q: How is the 12348 mounted in a rack?
A: The 12348 mounts vertically along the rear rail using three included plastic mounting clips — one at the bottom and two at the top. It does not occupy any rack unit space, keeping all U positions available for active equipment.
Q: Does the 12348 have network connectivity or remote monitoring?
A: No. The 12348 is a basic (non-managed, non-metered) PDU with a single green power-on LED indicator only. There is no network port, display, or remote monitoring capability. If you need metering or remote switching, consider a monitored or switched variant in the Vertiv rPDU line.
When integrators ask me about the 12348, the first thing I point out is the outlet density: 20 NEMA 5-20R receptacles at 2.8-inch spacing on a 66-inch vertical strip. That's the highest outlet count you'll get in a single rear-rail PDU at this power class, and it's exactly what you need when you're populating a 42U cabinet with 1U edge compute nodes, NVRs, or PoE switches where every device needs its own discrete outlet for clean circuit tracing.
Technical Highlights:
- Single 20A Thermal Breaker: All 20 outlets share one thermal breaker — tripping it kills the entire strip. Size your load to stay under 16A continuous (80% of 20A) to keep the breaker happy on sustained draws.
- L5-20P Twistlock Input: The locking input plug is the right call for data center aisles — vibration, cable pull, and accidental contact won't drop your rack. Requires a matching L5-20 receptacle on your UPS or ATS; verify your upstream device before ordering.
- TAA + Buy American Act COTS Compliant: USA manufacture means this qualifies for federal contracts and GSA schedule purchasing without a compliance exception — a procurement cycle saver on government or DoD edge deployments.
Deployment Considerations:
- The 10-foot input cord covers most 4-post cabinet configurations, but measure your UPS-to-PDU run before install — in deep enclosures with rear-mounted UPS bypass, you may need a cord management arm to avoid a sharp bend at the L5-20P head.
- No metering, no display, no network port: if your NOC needs per-outlet or per-PDU amperage visibility, this is the wrong model. Step up to a metered variant in the Vertiv rPDU family before the project locks in.
The 12348 is the right call for government-adjacent edge deployments — surveillance server rooms, federal agency IDF closets, or military installation network racks — where TAA compliance is non-negotiable and managed PDU attack surface needs to stay at zero.
