SDM120-Modbus / Mbus / Pulse

SINGLE PHASE MULTI-FUNCTION ENERGY METER

The SDM120-M is a MID Din Rail Single Phase Multi-function Solar PV /Zero Export Meter with RS485 output for PV metering. It measures active energy, reactive energy, current, voltage, power, power factor, frequency, etc. The units support Max. 45A direct connection, saving the cost and avoiding the trouble to connect external CTs. Two pulse outputs and 1 communication port (RS485 Modbus/DLT645) are provided for remote monitoring and setting, popular with single phase solar power system.

The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
