The reactiv e power auto-comensation controller is the auxiliary product for low voltage capa citor screen. According to the different demands of users,the comp any developed successfully the JKW5C,JKG2B,JKGF, JKL58-5,JKLl BF etc typ es ofin telligent series ofcontrollers.Number of the channels controlled is 4,6,8,10 and 12 av ailable.All ofthese devices are controlled by the micro-computer.With the advanced technology,they have complete range of functions,rather storng antinterfer ence ability, stable and reliable operation,accurate compensation and novel a pearance, so they are the preferred products ofcapacitor screen manu facturers．
