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.
