EASTRON SDM 630 MCT Wattmeter

Reference: 27000003

The Eastron SDM 630 MCT wattmeter is a three-phase meter that accurately displays the electric consumption of the installation, transmitting it to the inverter via the RS485 Modbus protocol. The wattmeter is compatible with all DEYE inverters.

The measurement of electricity consumption and the quick communication of the interface allows the inverter to restrict the power to what the installation (business, industry, residential) is currently using.

With this EASTRON SDM 630 MCT wattmeter, it is possible not to dump the excess of solar power into the grid.

The main features of this wattmeter are:

  • Three phase
  • RS485 Modbus
  • Up to 9999A with CT
  • 35mm DIN mounting
  • Higher accuracy than Class 1
  • Bidirectional measurement
