What this PDU is

The AP7911B is APC's Switched Rack PDU, 2U, 30A, 208V, 16 C13 outlets. It is a switched unit, which means network metering plus independent on/off control of every outlet. The B suffix on this part number is a commercial replacement for an obsoleted predecessor rather than a hardware revision. Every rated value carries across from the part it replaces; what changed is that the old number is discontinued. A rack PDU is the last link in the power chain and the one most often specified by habit. It decides how many devices a circuit can actually feed, whether you can see what they are drawing, and whether a hung box can be rebooted without somebody driving to the site.

Input and current rating

Input is 30 A at 200 V / 208 V / 230 V, through a NEMA L6-30P plug on a 12 ft (3.65 m) cord. Maximum output is 4992 VA. Those two current figures catch people out. The nameplate rating is what the plug and the internal path are built for; the derated figure is what North American practice allows you to draw continuously, and it is the one your circuit design and your capacity planning should use. Size the PDU to the breaker feeding it, not to the number of things you want to plug in. Outlets are cheap; amps are not, and a PDU with spare sockets on a full circuit is a trip waiting to happen.

Outlet configuration

The AP7911B provides 16 outlets: 16 x IEC 60320 C13. Check the receptacle types against the cords you actually own before ordering. C13 and C19 are not interchangeable, and neither are NEMA 5-15R and 5-20R in the direction that matters: a 5-20P plug will not enter a 5-15R socket. Where a rack mixes IEC and NEMA equipment, it is usually cleaner to standardise the PDU on the majority type and adapt the handful of outliers with proper cords rather than adapters. We can check the outlet mix against your equipment list before you order if that would help.

Rack mounting

This is a 2U rack horizontal unit, mounted across the rack on brackets like any other rack device. Dimensions are 3.5 in (89 mm) H x 17.5 in (445 mm) W x 10 in (254 mm) D. Net weight is 13.9 lb (6.32 kg). A horizontal PDU costs rack height, which is the argument against it in a full cabinet and no argument at all in one that is half empty. What it buys in exchange is a tidy single row of outlets at a known height, which is easier to label, easier to audit and easier to work on than a vertical strip in the rear channel.

Metering and control

It can be monitored through Web, Telnet, SNMP, SSH, or EcoStruxure IT Expert interfaces. A digital display shows aggregate current being used per bank. What that buys you in practice is a PDU with its own address, its own alert thresholds and its own log, so a circuit approaching its limit shows up before it trips rather than afterwards. It also means the rack's power draw is a number somebody can look up rather than a clamp meter and a site visit. Switched units go further than measurement: each outlet can be turned off and on across the network, which turns a hung appliance into a two-minute job rather than a site visit, and lets an unused outlet be locked out entirely.

Environment and siting

Operating temperature is 32 to 113 F (0 to 45 C). That range is wider than most rack equipment tolerates, which is the point: a PDU sits in the hot aisle side of the cabinet and has to keep working when the surrounding air is doing something the servers would object to. It is still worth siting sensibly. A strip pressed against a blanking panel in a badly baffled cabinet runs hotter than the room does, and heat shortens the life of the switching relays more than anything else will.

In the box

APC lists the following in the carton for this part number: Documentation CD, Installation guide and Rack Mounting brackets. Warranty is 24 months. Carton contents vary more across this range than you would expect from one product family, and they are not safely copied sideways between part numbers, so the list above is what the current sheet for this exact model prints rather than a tidier list assembled from a sibling. Power cords for the connected equipment are not included on any model in this range; budget for those separately if the rack is a new build.

For a rack that needs 16 outlets of switched distribution at 30 A, the APC AP7911B is the right part and we hold it in stock. Contact us to learn more or secure this solution for your business today.
