The Sentry Cabinet Power Distribution Unit (CDU) is an intelligent PDU with local LED input current monitoring, allowing network engineers to utilize the Cabinet PDUs True RMS Power Monitor to precisely measure the current (in amps) that network devices are drawing on the power circuit.

As new equipment units are added to the power drop, immediately observe its impact on the cumulative current draw. This allows the engineer to safely load each circuit to its maximum allowable load capacity without the danger of overloading the power circuit.
