Click：627
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
