Reactive Power Auto-Compensation Controller (JKGM-12)

Product Description

JKG Series reactive power auto-compensation controller is designed to rise the system power factor upto a user´ S appointed range when normal load. It can adjust the low load closedown, functionally prevent from its cast and concussion and it has strong anti-jamming capability and insensitive to harmonic wave.
