Metered 120V, 20A 12 x 5-20R, Zero U
This Server Technology® Metered PDU is an intelligent PDU with local LED input current monitoring, allowing network engineers to precisely measure the current (in amps) that network devices are drawing on the power circuit. As new servers and devices are added to the power drop, the engineer can immediately observe the impact on the cumulative current draw. This allows each circuit to be safely loaded to its maximum allowable load capacity without the danger of overloading the power circuit.

A 30A version is available here; 208V versions are also available as well.
