Zero-U vertical rack PDU

This APC AP9551 is a basic power distribution unit that mounts vertically in a zero-U profile. It accepts 100 V to 120 V input through a NEMA L5-20P plug on a 12 ft cord and delivers 120 V output across fourteen NEMA 5-15R receptacles. The unit is rated for 2400 VA and carries cUL Recognized, CSA, UL 1363 and UL Recognized certifications.

Suited for single-source rack power.

Installers who need a low-cost way to distribute a single 20 A branch circuit to multiple devices in a rack will find the fourteen outlets and tool-less mounting kit convenient. Buyers who require local or remote current metering, outlet-level switching or environmental sensors should look at a different model because this basic PDU provides none of those functions.

20 A input with 16 A derated limit

The regulatory derated input current is 16 A, so continuous loads must stay at or below that level even though the plug and breaker are rated for 20 A. Exceeding 16 A on a sustained basis would violate the safety listing and risk nuisance tripping.

Questions about this item

What rack space does the 0U vertical AP9551 occupy?

The AP9551 mounts vertically in a zero-rack-unit footprint so it consumes no horizontal U-space inside the cabinet.

How is the NEMA L5-20P input cord connected to the facility circuit?

Plug the 12 ft NEMA L5-20P cord into a matching 20 A locking receptacle; the step often missed is ensuring the branch circuit is derated to 16 A per regulatory limits.

What ongoing maintenance does the basic PDU require?

No user-serviceable parts exist; periodically verify the 14 NEMA 5-15R outlets and the overload protection indicator remain functional and connections stay tight.
