APC by Schneider Electric AP7581 2U Rack-Mount Power Distribution Unit
Overview
The AP7581 is a 2U rack-mount PDU from APC by Schneider Electric designed to distribute 208V power across four outlets in equipment racks where a dedicated rack power distribution solution is required. It accepts input via a NEMA L14-30P plug — the locking twist-lock configuration common on facility-grade 208V circuits — so it plugs directly into compatible PDU-rated receptacles without adapters. With a 28-inch cord, the AP7581 reaches standard overhead or underfloor power drops in typical two-post or four-post rack enclosures. If you're building out a rack for NVRs, network switches, or APC by Schneider Electric infrastructure equipment that runs on 208V, this unit handles the branch-circuit termination cleanly in 2U of rack space. The four-outlet configuration suits smaller equipment densities — server rooms, security head-end closets, or satellite comms racks where you need reliable 208V distribution without the footprint of a high-density PDU.
Compatibility
The AP7581 is compatible with standard 19-inch EIA rack enclosures including APC NetShelter SX, SV, and VX series, as well as third-party racks accepting 2U rackmount accessories. Input compatibility requires a 208V circuit terminated with a NEMA L14-30P receptacle — confirm your facility's branch circuit matches before ordering, as L14-30P is a 30A locking plug specific to 120/208V two-phase configurations. Downstream outlets accommodate standard NVR and server equipment power cords rated for 208V operation. Pair with an APC UPS upstream for protected 208V distribution to mission-critical recording or switching infrastructure.
Installation Notes
Mount horizontally in a standard 19-inch rack using the integrated 2U rackmount ears. The 28-inch input cord length determines how close the rack must sit to the facility power receptacle — measure the distance to your L14-30P wall or floor outlet before positioning the rack. Verify that the upstream circuit breaker and receptacle are rated for the aggregate load of all four connected devices; the L14-30P connection is rated for 30A at 208V, but local electrical code may require derating to 80% continuous load (24A). No additional tools or hardware beyond standard rack screws are required for mounting.
