3 phase M-bus energy meter SDM630M

3 phase M-bus energy meter SDM630M is a three phase multifunction DIN rail meter. It can measure and display the characteristic of 1p2w,3p3wand 3p4wsupplies, including voltage, current, power, active and reactive energy imported or exported. Energy is measured in terms of kWh, kVarh. Max 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 the power the meter. The required current inputs are obtained via current transformers. This meter can be configurable to work with a wide range of CTs, giving the unit a wide range of operation. Build-in interface provides pulse and RS485 Modbus RTU/Mbus outputs. And the configuration is password protected.
