The MC3D01RM is digital three phase 4 wire energy meter with a white back-lighted LCD screen for perfect reading.
The unit measures and displays active energy (kWh) and power ( W), imported and exported. A resettable partial
energy is provided, so the user can easily check the energy imported and energy exported during a certain period.
MC3D01RM supports max.100A direct connection, saves the cost and avoid the trouble to connect external CTs,
giving the unit a cost-effective and east operation. Built-in interfaces provides pulse and RS485 Modbus RTU outputs.
Configuration is password protected.
