JKG/W intelligent reactive power auto-compensatio

JKG Series intelligent controller is also called reactive power auto-compensation controller. It is designed to rise the system power factor upto a users 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. Technical data: 1. Basic data: Rated voltage: AC220/380+-10% Rated current: AC 0-5A Rated frequency: 50Hz+-5% 2. Controlling data: Sensitivity: 200mA(100-999mA) COSΦpreset: 0.80-0.99;preset of leave factory:0.92 Cast and cut delay: 1-120s Over voltage protection: 220(220-250V),preset of leave factory:240V; 380(400-450V),preset of leave factory:420V; 3.
