Vertiv Rpdu Switched Unit Level Monitoring EC 30A 120V 2.8KW Horizontal (12) NEMA - VP5N31A0

Vertiv VP5N31A0 Switched Rack PDU with Unit-Level Monitoring

Overview

The Vertiv VP5N31A0 is a 1U horizontal switched rack PDU from the Geist product line, delivering 30A at 120V across 12 NEMA 5-20R receptacles — purpose-built for data center racks, edge deployments, and network closets where remote outlet control and accurate power visibility are non-negotiable. At 2.8kW capacity with a NEMA L5-30P input plug, this unit handles a densely loaded 1U rack shelf without requiring a higher-voltage circuit.

What separates the VP5N31A0 from a basic metered PDU is the combination of outlet-level switching and ±1% power monitoring accuracy — you get both the ability to cut power to individual devices remotely and reliable kW readings you can actually budget against. That pairing matters in colocation environments where tenants are billed per kWh and in enterprise server rooms where you need a defensible power audit trail.

Key Features

• 12 NEMA 5-20R Outlets with Individual Switching: Each outlet can be toggled on or off remotely via the dual Ethernet management interface. This eliminates the need for a technician on-site to hard-reset a locked-up server or network device — particularly valuable in remote edge closets or after-hours incidents.
• ±1% Power Monitoring Accuracy: Most basic metered PDUs report power at ±2–3% tolerance. The VP5N31A0's tighter ±1% accuracy is meaningful when you're tracking actual load against circuit capacity or producing energy reports for facilities management or tenant billing.
• 2.8kW / 30A Input via NEMA L5-30P: The locking L5-30P plug connects to a dedicated 30A 120V branch circuit — plan for a 24A usable draw (80% NEC de-rating) before alarms. At 2.8kW rated capacity, this PDU suits mid-density compute racks rather than high-density GPU or storage arrays pulling 5kW+.
• Dual Ethernet Ports: Two network ports support daisy-chain or dual-homed management configurations. If your management VLAN has a single network failure, the second port provides a backup path — a straightforward reliability improvement over single-port PDU management cards.
• 128×128 LCD Touchscreen: Local display of input power, current load, and outlet status without requiring a laptop or terminal connection. Useful during initial commissioning or when network management is temporarily unavailable.
• Environmental Sensor Port: Connect a temperature/humidity sensor to monitor rack microclimate data through the same management interface used for power. Consolidates environmental and power telemetry into one management pane rather than deploying separate sensor hardware.
• Hot-Swappable Monitoring Device: The monitoring module can be replaced without powering down the outlets — critical in environments where rack downtime is not acceptable during a management card failure or firmware update cycle.
• Bi-Stable Latching Relays: Outlet state (on/off) is maintained through a power interruption to the PDU itself. If the PDU loses input power and recovers, outlets return to their last configured state rather than defaulting to on — prevents unintended device restarts in controlled shutdown scenarios.
• Secure Boot: Firmware integrity is validated at startup, reducing the attack surface against firmware-level tampering. Relevant in environments with strict IT security baselines or compliance requirements.
• TAA-Compliant: Meets Trade Agreements Act requirements, making the VP5N31A0 eligible for federal government procurement and GSA schedule purchasing without additional country-of-origin review.
• UL-Listed, RoHS Certified, ANSI & IEC Standards: Third-party safety certification (UL) confirms the unit meets North American electrical safety standards. RoHS certification addresses hazardous substance restrictions for deployments with environmental compliance requirements.
• 1U Horizontal Form Factor, 17 × 12 × 1.72 in: Mounts in a standard 1U rackmount position. At 12 lbs, it doesn't require special rail kits or additional mounting support beyond standard rack ears — straightforward installation in any rack PDU slot.

Integration and Compatibility

The VP5N31A0 connects to 30A 120V branch circuits terminated with a NEMA L5-30P receptacle — verify your PDU breaker panel or in-row power strip supports this connector before ordering. The 12 NEMA 5-20R output receptacles accommodate standard 5-20P plugs used on most 1U servers, network switches, and desktop compute devices; devices requiring C13 or C19 connectors will need plug adapters, which are not included.

Dual Ethernet management ports integrate with DCIM platforms, SNMP-capable NMS systems, and proprietary Vertiv management software. For teams running a DCIM or BMS overlay, the environmental sensor port expands the unit's data output without additional management endpoints. Review network management solutions compatible with Vertiv's PDU management stack to plan your monitoring architecture. TAA compliance makes this unit a viable candidate for federal, SLED, and defense contractor deployments — pair with rackmount compute or network gear requiring the same procurement standard.

Frequently Asked Questions

Q: What input plug does the VP5N31A0 use, and what circuit does it require?

A: The VP5N31A0 uses a NEMA L5-30P locking input plug and requires a dedicated 30A 120V branch circuit. Per NEC 80% continuous load guidelines, plan for a maximum sustained draw of 24A (2.88kW) rather than the full 30A rated input.

Q: Can I switch individual outlets remotely on the VP5N31A0?

A: Yes. The VP5N31A0 supports outlet-level switching across all 12 NEMA 5-20R receptacles via its dual Ethernet management interface, allowing remote power cycling or shutdown of individual devices without on-site access.

Q: Is the VP5N31A0 TAA-compliant for government procurement?

A: Yes. The VP5N31A0 is TAA-compliant, meeting Trade Agreements Act requirements for federal government and GSA schedule purchasing.

Q: What happens to outlet states if the VP5N31A0 loses power and recovers?

A: The VP5N31A0 uses bi-stable latching relays, which means each outlet returns to its last configured state (on or off) after a power interruption and recovery — outlets do not default to on, preventing unintended device restarts.

Q: What is the power monitoring accuracy of the VP5N31A0?

A: The VP5N31A0 provides ±1% power monitoring accuracy at the unit (input) level, suitable for energy auditing, capacity planning, and tenant billing applications.

Q: What is the warranty on the VP5N31A0?

A: The VP5N31A0 carries a 5-year limited warranty from Vertiv.

The VP5N31A0 is the model I recommend when a team needs real outlet-level control — not just monitoring — in a 1U footprint on a standard 30A 120V circuit. The ±1% power accuracy is what makes this unit useful beyond basic remote switching; you're getting readings tight enough to use for capacity planning and energy cost allocation, not just ballpark load estimation.

Technical Highlights:

• Bi-Stable Latching Relays: Outlet state persists through PDU power loss and recovery — in a brownout-prone facility or during UPS transfer events, devices return to their pre-configured state instead of mass-restarting, which matters when you have sequenced boot dependencies.
• Hot-Swappable Monitoring Module: You can pull and replace the management card without cutting power to the outlets — a meaningful operational advantage in 24/7 environments where any outlet downtime triggers an incident ticket.
• Dual Ethernet Ports: Supports daisy-chain topology across multiple PDUs or a dual-homed management configuration — reduces the number of switch ports consumed by PDU management in high-density deployments with many PDUs per rack row.

Deployment Considerations:

• The NEMA 5-20R outlets are the right fit for standard 1U servers and network gear, but confirm your device inventory before ordering — any equipment with IEC C13 or C14 plugs will need adapters that are not included with the unit.
• At 30A input with an 80% NEC de-rating, your practical ceiling is 24A continuous. If your rack is already pulling 20A+ from other sources, size up to a higher-amperage model rather than running close to the de-rated limit.

This PDU is a solid fit for colocation cage deployments and enterprise network closets where remote hands are expensive or unavailable — the outlet switching, ±1% power accuracy, and bi-stable relays together eliminate the most common reasons you'd otherwise need to dispatch someone to the rack.
