The Sentry 12V Cabinet Power Distribution Unit (CDU) is an intelligent PDU with local LED input current monitoring, allowing network engineers to utilize the Cabinet PDU''s 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.Our Cabinet PDUs meet new UL 60950-1 Branch Circuit Protection requirements. Each branch circuit utilizes a Bussman SC fuse as an Overcurrent Protection Device (OCPD). Now you can safely run 30-amp power drops to your server cabinet where individual outlet receptacles have lower output ratings (i.e., 20-amps).
