Accurate Low Voltage Protection Devices , Reactive Power Compensation Controller
Accurate Low Voltage Protection Devices , Reactive Power Compensation Controller
General Description
The reactive power auto- compensation controller is the auxiliary product for low voltage capacitor screen. According to the different
demands of user, the company developed successfully the JKL5C, JKW58, RRCF, JKW9F, JKW5C types of intelligent controller series;
Number of the channels controlled is 4,6,8,10 and 12 available. All of these devices are controlled by the microcomputer, with the advanced
technology, they have complete range of functions, rather strong anti-interference ability, stable and reliable operation, accurate compensation
and novel appearance, so they are the preferred products of capacitor screen manufactuers
