APC NetShelter Rack PDU Advanced, Switched Metered Outlet, 3Phase, 8.6kW, 208V 30A, 48 Outlets, L21-30P

The APC APDU10351SM is a three-phase rack power distribution unit that brings precise metering and per-outlet control to servers, storage, and network equipment. It arrives ready to deliver up to 8.6 kW at 208 V through a NEMA L21-30P input, giving administrators the capacity they need without sacrificing visibility or flexibility.

Forty-eight outlets line the strip, each one switchable from the web interface or through popular data center management platforms. That means you can cycle a frozen server, lock power to critical gear, or delay outlet start-up after an outage without stepping into the aisle.

Every receptacle is a four-in-one design that accepts C13, C19, C15, or C21 plugs, so one PDU can support mixed hardware ranges from blade chassis to small form factor appliances. An alternating phase layout keeps cord runs short and helps balance loads, a practical advantage in racks that combine single- and three-phase devices.

The integrated Network Management Card monitors current, voltage, power, and energy with one-percent accuracy. It connects over gigabit Ethernet and offers a second port for daisy-chaining another PDU or creating a redundant link. Because the card is field-replaceable, you can swap it for an upgrade or repair without interrupting power to attached equipment.

Rated to operate at temperatures up to 140 °F, the APDU10351SM stands up to dense, hot aisles in modern data centers, edge closets, and engineering labs. By combining flexible outlets, accurate metering, and remote switching, it helps IT teams prevent overloads, streamline maintenance, and keep critical systems online with fewer on-site visits.
