KE8704 is equipped with advanced digital technique, computer technology and modular design to meet the various demands of customers; it is wildly used in power grid companies, meter manufacturing companies and institutes of metrology.

The main features of KE8704:

Simultaneous output of three voltage signal and three current signal for the test of the three phase or single phase meters
2^nd- 21^st harmonics could be generated and the amplitude and the phase could be freely programmable
Stable and accurate output of current, voltage and harmonic
Auto protection of short circuit of voltage, open circuit of current, and overload and sound alarm for it.
Full automatic or manual operation
The working status could be shown by the external indication light.
