General

AC precision power distribution monitoring unit BCM101 series products serve for the monitoring of power parameters of AC power array cabinets in data center, measuring the voltage, current, energy and harmonic of incoming line and feeder line branches as well as on-off state of all the circuit breakers, and have tripping alarm function; each output circuit has two-level user-defined overcurrent alarm to prevent potential power fault. The product is equipped with 7in LCD touch screen, and has Ethernet communication interface to facilitate the access of other systems.
