3 Phase 4 wire Energy Meter Solar PV Energy Meter RTU Digital Meter SDM630Modbus
Description: The 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 & EXP Two pulse outputs Mbus Din rail mounting 35mm 100A direct connection Specification: Voltage AC (Un): 230/400V Base Current (Ib): 10A Max. Current (Imax): 100A Mini Current (Imin): 0.5A Starting current: 0.4% of Ib Power consumption:<2W/10VA Frequency: 50/60Hz (±10%) AC voltage withstand: 4KV for 1 minute Impulse voltage withstand: 6KV-1.2uS wavform Overcurrent withstand: 30Imax for 0.01s Pulse output rate: 1000imp/kWh (default); 100/10/1 imp/kWh/kVarh (configurable) Display: LCD with blue backlight, Max.
