2. Technical Parameters
2.1. Operating Voltage
Rated voltage Un
3×230/400 V
Operating voltage range
60% Un ~ 130% Un
The meter can work normally within the operating voltage range.
Limited range of operating voltage 0 Un ~ 190% Un
Within this limited operating voltage range, the meter will show no damage. It can
guarantee metering during normal display, but cannot ensure the metering accuracy
class.
Meanwhile, the load control equipment cannot operate. After the operating voltage returns
to normal, the meter can work normally and the accuracy class will remain unchanged.
2.2. Current Parameters
Imax 100 A
Starting current (0.4%Ib)
40 mA
Metering current range 40 mA ~ 100 A
Common current specification 10(100) A
2.3. Frequency Parameters
Rated frequency fn 50 Hz
Frequency application range 47.5 Hz ~ 52.5 Hz
2.4. Self- power Consumption of Meter
Power consumption of voltage circuit
≤2 W 6 VA
Power consumption of current circuit
≤2.5 VA
2.5. Active Metering Accuracy
The accuracy of active energy measurement of APL SEM 3P V2 conforms to
IEC62053-21 Class 1.0.
