Product Description3 Phase 4 wire Energy Meter Solar PV Energy Meter RTU Digital Meter SDM630ModbusThe SDM630Modbus 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 60 minutes. In order to measure energy,the unit requires voltage and current inputs in addition to the supply required to power the product.SDM630Mbus supports max. 100A 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 Mbus outputs.Configuration is password protected.Measures kWh Kvarh, KW, Kvar, KVA, PF, Hz, dmd, V, A, etc.Bi-directional measurement IMP and EXPTwo pulse outputsMbusDin rail mounting 35mm100A direct connectionSpecification:Voltage AC (Un): 230/400VBase Current (Ib): 10AMax.
