Main functions

1 . Measurement function: measure active energy and reactive energy

2 . Supplied with three-phase power, any one phase or two phases fail, the accuracy of measurement isn' t affected.

3 . Output interface: active and reactive and passive pulse output interface with optical coupling isolation

4 . Phase failure indication: Three luminescent tubes

indicates the phase failure,they repr esentsA phase, B phase,C phase respectively,some phase faiures, its corres-ponding indicat or lamp goes out.
