Switched 1U PDU with Eight C13 Outlets

This APC AP7921B is a switched rack power distribution unit that occupies one rack unit and provides eight IEC 320 C13 outlets. It accepts 200V to 230V input through an IEC-320 C20 plug on an 8.2 ft cord and delivers up to 3680 VA. Remote outlet switching and a local current display let administrators manage loads from anywhere.

Suits Managed Racks; Not for Unmetered Basic Power

Network managers who need per-outlet control, multi-tier user access and real-time load monitoring will use the switched features daily. The unit also carries cUL, CE, CSA and VDE certifications for regulated environments. Builders who only need simple power distribution without remote switching or a current display should consider a basic PDU instead.

20 A Maximum Input with 16 A Derated Limit

The PDU is rated for a maximum input current of 20 A, but regulatory derating restricts continuous draw to 16 A. This 4 A gap determines how many devices you can safely connect on a single branch circuit. Exceeding the derated value risks tripping upstream protection even though the hardware tolerates the higher peak.

Questions about this item

What rack height does the 1U switched PDU occupy and what input plug does it use?

The unit fits a standard 1U rack space and connects via an IEC-320 C20 inlet on an 8.2 ft cord.

How is the PDU mounted and which step is often missed during setup?

It mounts horizontally using the supplied rack brackets; the step often missed is securing the cord retention bracket to prevent the C20 plug from pulling loose.

What environmental limits should be monitored for long-term operation?

Operate between 0 and 45 °C with humidity up to 95 % non-condensing; storage allows -25 to 65 °C and the same humidity range.
