Features
1.Starting: when reference voltage, reference frequency and power factor is under 1.0 condition, meter cl 1 is 0.4%Ib, and meter cl 2 is 0.5%Ib , the meter can start and normally measure. 3 phase 4 wire energy meter connection
2.Shunt running: the meter has anti-shunt running logic circuit. when voltage circuit plus 1.15 times reference voltage and there is no current in current circuit, the test output of meter will be no more than one pulse.
3.Power consumption：≤1W（5VA） 3 phase 4 wire energy meter connection
4. Environment condition
standard working temperature：-25℃～55℃ limit of working temperature：-25℃～60℃
note: Special requirement of working temperature limit：-40℃～70℃
