JKWF series controller regards 8 single chip microcomputer as core, adopt the control scheme of phase splitting sampling and compensation and common compensation and plase splitting compensated together, very suitable fro reactive compensation with 50HZ 0.4kv three phase load imbalance power system

1. Function characteristic
A. LED display three phase voltage, current, active power, reactive power, current power, power factor, and electric net frequency and controll data and so on (using this controller in the capacitor bank and compensation equipment, so you would not assemble current meter and voltage meter and universal switch in the capacitor bank )
B. It have anti interference ablility, it can resisted directly input 2000V impulse. It still work, and it would not stop suddently, and keep before data,
C. It is reactive power, control accuracy is very high
D. User can remend the control data according themselves data, power is off, the data keep
E. It has auto discriminating phase function, (fetch signing will keep same state )
F. Current sampling sign input resistance is less than 0.5?, it can be taken out from measuring loops directly
G. It have over voltage, under voltage and lack phase protection function
H. Compensation mode: Every phase compensation, everyphase and three phase compensation, three phase compensation
I. Output way: Staic state, dynamic state, compound etc
Output step: 1-12 step
