Single/Three Phase Multi-Function Din Rail Energy Meter , Digital Watt Hour Meter With Modbus Output SDM630-Modbus

AC voltage, AC current , active power, apparent power and power factor


The SDM630 Meter measures and displays the characteristics of single phase two wires(1p2w) , three phase three wires(3p3w,) and three phase four wires(3p4w) supplies, including voltage, frequency, current, power ,active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to 60 minutes. In order to measure energy,the unit requires voltage and current inputs in addition to the supply required to power the product.



SDM630Modbus supports max. 100A direct connection,saves the cost and avoid the trouble to connect external CTs,giving the unit a cost-effective and easy operation.Built-in interfaces provides pulse and RS485 Modbus RTU outputs.Configuration is password protected.
