SDM220MT is a multi-tariff RS485 modbus 100A din rail single phase MID energy meter. The unit measures active energy, reactive energy, current,voltage, power, power factor, frequency, demand, etc. Bi-directional measurement makes this unit an ideal choice for Solar PV measurement.Build-in interface provides pulse and RS485 Modbus RTU outputs.
The multi-tariff function is used to measure the energy consumed in different time zone. It supports Max. 4 tariffs and 10 time segments setting. The tariffs and time segments can be set via RS485 communication.
The SSDM220 Series meters has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU.The EU Type Examination Certificate Number is 0120/SGS0172.
