The SDM630MCT-DI is CT Operated Digital Input RS485 Din Rail Three Phase UL Energy Meter. This unit measures and displays the characteristics of 1P2W, 3P3W and 3P4W networks. The measuring parameters include voltage (V), current (A), frequency (Hz), power(kW/kVA/kVAr), power factor (PF), imported, exported and total energy (kWh/kVArh).

SDM630MCT-DI also comes with a complete comms capability with built-in RS485 Modbus RTU outputs and 2 digital inputs.

The requisite current input(S) are obtained via 1A/5A output current transformers (CT), this meter can be configured to work with a wide range of CTs, giving the unit a wide range of opration. Configuration is password protected.

SDM630MCT-DI has been assessed and certified as meeting the requirements of UL 61010.
