KE8702 Large Output Three Phase Power Source

KE8702 is a three phase computer controlled or manual controlled power source, designed for use in meter test systems and in the laboratory. It generates and delivers high power voltage and current signals stably for high volume calibration and testing of electricity meters and measuring and protecting devices.

Production features:

1. High stability of voltage, current, harmonic output
2. Simultaneous output of three voltage signal and three current signal for the test of the three phase or single phase meters
3. 2^nd- 21^st harmonics could be generated and the amplitude and the phase could be freely programmable
4. Perfect protective alarming function, auto protection of short circuit of voltage, open circuit of current, and overload.
5. Using the aluminum alloy as the shell material to reduce the total weight of the power source.
6. Full automatic or manual operation
7. The working status could be shown by the external indication light.
