Product information

SDM230Modbus is an advanced digital single phase multi-function energy meter, which measures upto 100A direct load. The SDM230modbus has 15 measured paramters and 4 different kWh measurment modes which has been designed around the development of regeneration, such as solar and battery storage. The means the pulsed output can be configured for the following.

  • Import +Export = Total kWh
  • Export - Import =Total kWh (Nett)
  • Import = Total kWh
  • Export = Total kWh 

A  communication port is provided, RS485 Modbus RTU or M-bus EN13757-3 and Communication parameters are password protected in the setup mode. The SDM230-2T can measure energy from two differen tpower supplies acting as a dual tarriff meter.
