400-996-9296
The SDM230-NMI-2 is a 50mS Update Single Phase Multi-function Energy Meter with 2X RS485 Port. The meter measures active energy (kWh), reactive energy(kVArh), current, voltage, power, power factor, frequency, etc. The unit support Max. 100A direct connection. 2x RS485 Modbus communication ports are provided for remote monitoring and setting. Bi-directional measurement makes it an ideal choice for solar PV measurement solutions.
The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
