JKW2B reactive power auto-compensation controller

A) General Description
  The reactive power auto-compensation controller is the auxiliary product for low voltage capacitor screen. According to the different demands of users, our company developed successfully the JKL1B, JKG2B, JKGF, JKL5C, JKL8C, JKW5C, and JKW8C intelligent series of controller; Number of the channels controlled is 2,4,6,8,10 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 manufacturers.
