KE870x
Three Phase Stable Power Source
KE870x series three phase power source 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.

Highlight

² High stability

² Simultaneous output of three voltage signal and three current signal for the test of the three phase or single phase meters

² 2nd- 21st harmonics could be generated and the amplitude and the phase could be freely programmable

² Perfect protective alarming function, auto protection of short circuit of voltage, open circuit of current, and overload.

² Full automatic or manual operation

² The working status could be shown by the external indication light.
