This is an integrated solution for monitoring multi-circuits and mains by using a single meter. The meter is designed for use in new build and is used for critical power operations in data centres and energy management in buildings. It offers class 1 (1 %) power and energy system accuracy (100A solid core current transformers) on all branch channels. The BCPM monitors both the 42 branch circuits and mains values, incoming power and energy. All to provide information on the complete Power Distribution Unit. Full alarming capabilities ensure that potential issues are dealt with before they become problems. Communication enabled with serial connection for either Modbus RTU or BACnet MS/TP, and an Ethernet connection for Modbus TCP, BACnet IP and SNMP. The meter need to be powered by a 100V AC to 277V AC supply source. Include 2 21-CTs board strips with 3/4inch (19mm) spacing between each CT connectors, for 42 circuits. The device dimensions are 353mm in width, 253mm in height, 71mm in depth and weight 1.5 kilograms.
