SDM630-M

THREE PHASE MULTI-FUNCTION ENERGY METER

SDM630-M is RS485 Modbus 100A Din Rail Three Phase MID Energy Meter.

The unit can measure and display 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.

SDM630-M 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.

It has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU.
