Vertiv VP4N31A6 Monitored Horizontal Rack PDU
Overview
The VP4N31A6 is a unit-level monitored, horizontal rack PDU rated at 30A with a 277/480V WYE three-phase input and 277V output — built for high-density data center and critical infrastructure deployments where branch-circuit-level power visibility matters. At 19.9kW capacity across 12 Saf-D-Grid Series 400 outlets, it targets dense compute and AI/GPU rack environments where standard 120/208V PDUs hit their ceiling and facility power is delivered at medium voltage. The horizontal 1U form factor (1.7" H × 17.1" W × 12" D) integrates into standard 19-inch rack rails without consuming deep cabinet space.
Compatibility
Designed for deployment in rack environments fed by 277/480V WYE three-phase power distribution — common in purpose-built data halls, colocation facilities, and large enterprise server rooms where high-density power is delivered at medium voltage. The 12 Saf-D-Grid Series 400 outlets are specific to Vertiv's Vertiv power distribution ecosystem; equipment connected to this rack PDU must be fitted with compatible Saf-D-Grid Series 400 plugs or adapters. This unit is not interchangeable with standard NEMA or IEC C13/C19 outlet PDUs — confirm outlet compatibility before specifying. The monitored (unit-level) feature set provides per-PDU power metering visible to your DCIM or infrastructure management platform, enabling capacity planning and overload alerting at the distribution unit level.
Installation Notes
At 30 lbs, the VP4N31A6 requires two-person installation for safe rack mounting. The horizontal orientation suits standard 19-inch server rack cabinets; verify that your cabinet supports the 12-inch depth and provides the necessary 277/480V WYE branch circuit with appropriate upstream overcurrent protection rated for 30A. Input connection is via the facility's branch circuit — confirm local electrical code compliance and use a qualified electrician for medium-voltage termination. All 12 outlets are Saf-D-Grid Series 400; connected equipment must carry matching plugs — this is a hard compatibility constraint, not a preference.
