Three phase multifunction energy meter, Bi-directional for PV solar

The SDM***-Modbus measures and displays the characteristics of single phase two wires (1p2w), three phase three wires (3p3w,) and three phase four wires(3p4w) supplies, including voltage, frequency, current, power ,active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to *0 minutes. In order to measure energy, the unit requires voltage and current s in addition to the supply required to power the product.

SDM***-Modbus supports max. **0A direct connection, saves the cost and avoid the trouble to connect external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces provides pulse and RS**5 Modbus RTU outputs. Configuration is password protected.
