Click:680
Features:
Measurement:three-phase phase voltage, line voltage;total active power, reactive power,power factor,apparent power,active electrical energy, reactive electrical energy.
Display:LED display or LCD HD display
Communication:RS485 communication, MODBUS-RTU protocol.
Output: 2 loops electrical pulse output( pulse constant:5000imp/kwh)
Basic function: input signals through CT/PT directly;set and reset CT/PT freely.
Multi-rate:With two sets of time sections sheets, 4 kinds of rates, 12 hours of multi-rate charging function The quantity of electric power turn to store automatically at a specified date every month, the historical data can save for 3 months.High-precision clock, guarantee that timing error is less than 0.5 seconds/day
