Rack PDU for 120 V environments
The APC AP9551 is a basic power distribution unit designed to deliver 120 V power to equipment mounted in a standard rack or enclosure. It suits small branch offices and large datacentres alike where a simple, reliable power strip is required.
Sustained load behaviour
The unit provides a continuous 20 A rating across its fourteen NEMA 5-15 receptacles, allowing multiple servers or network devices to draw power simultaneously without exceeding the rated capacity. Basic operation means no metering or switching functions are present.
Thermals noise and power draw
Passive construction eliminates fan noise entirely, so the PDU adds no audible sound to the rack environment. Heat output is limited to the normal losses of power distribution, and the unit draws no power for its own operation beyond the connected load.

Questions about this item
Does the AP9551 PDU produce any fan noise or heat when loaded to 20 A all day?
The AP9551 is a basic passive power strip with no fans, so it adds no audible noise and only the minimal heat from the 14 NEMA 5-15 outlets carrying up to 20 A at 120 V.
What plug or inlet must my rack circuit provide for the AP9551 to connect?
The unit requires a 20 A 120 V supply terminated in a NEMA L5-20P locking plug to match its inlet.
Will the AP9551’s 14 NEMA 5-15 outlets accept older servers that still use 5-15P cords?
Yes, every outlet is a standard NEMA 5-15R receptacle, so legacy equipment with 5-15P plugs connects directly.
