SDM72D-M

THREE PHASE ENERGY METER

SDM72D-M is RS485 Modbus Din Rail Three Phase MID Energy Meter.

The unit measures and displays voltage, current, frequency, power factor, active power, reactive power, active energy and reactive energy, etc. A resettable partial energy is provided, so the user can easily check the active energy imported and active energy exported during a certain period.

It supports max.100A direct connection, saving the cost and avoiding the trouble to connect external CTs, giving the unit a cost-effective and east operation. Built-in interfaces provide pulse and RS485 Modbus RTU outputs.

It has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU. The instrument tracebale number is T12831.
