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 allow the monitoring of the branch circuits current only, for a maximum of 42 circuits. 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 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. This version is for 42 circuits, but do not include branch current transformers nor ribbon. The device dimensions are 228mm in width, 146mm in height and weight 1.5 kilograms.
