Utmost worki ng voltage: 0.7~1.2 of reference voltage
2. Insulation voltage: 2000VAC
3. Voltage circuit power consumption: 2 W and 10VA
4. Normal working temperature(outdoor): -25 ~55
Utmost working temperature(outdoor): -45 ~70
Storage and transport temperature(outdoor): -40 ~70

1. Energy measurement
It can measure the forward and reverse electric quantity, display the measurement and accu mulati on of re verse e nergy
and forward energy, also can indicate the reverse energy amount. Meanwhile, it can prevent the electricity being
theft by reversing the current.
2. Detection interface
There is a detection terminal of photoelectric isolation and pulse output, for checking the meter.
3. Communication interface
There is a RS485 communication interface, convenience for the centralized meter reading syste m.
4. Protection measures
The product internal design has the protection circuit of resisting the lightning strike and high-frequency
electromagnetic interference.
5. Wide range of working voltage
In the state of working at 1.5Un over voltage, three luminotrons, representing phase A, phase Band phase C respectively,
indicates whether the phase failure happens, if any phase is fail ure, the co rresponding indicator lamp goes o ut.
