Introduction The MCM400 main for Non - industrial users sub-metering, use ../100mA or 0.333mV CT, split core design easy for install, Din-rail mounting for every style of electrical panel in build. The unit performs real-time metering, measures energy consumption, multi-tariff time-of-use (TOU) and monitors power quality max 4 channels circuit for three phase circuits, with LCD screen and keypad for easy for configuration. RS485 port can send out collected value to remote host. Enable reliable monitoring of building electrical loads with a low installation cost-per-point by combining sub-metering. It is ideal for multi-tenant or departmental metering applications within office towers, condominiums, apartment buildings, shopping centers and other multi-user environments.
