This is an integrated solution for monitoring multi-circuits and mains by using a single meter. The meter is designed for retrofit 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 (including 50A, 100A or 200A split-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. Adapter boards with terminals for split-core CTs can be mounted using DIN-rail, Snaptrack or on a common mounting plate with the main board Full alarming capabilities ensure that potential issues are dealt with before they become problems. Communication enabled with a RS485 serial port and the Modbus protocol support, more communication options with the gateway H8951. The meter need to be powered by a 90V AC to 277V AC supply source. Include 50A branch CTs with 2 meters leads and 1.8 meters round ribbon cables, for 42 split-core current transformers. The device dimensions are 228mm in width, 146mm in height and weight 1.5 kilograms.
