General Description
The automatic reactive power compensation controller is an auxiliary product for the low voltage capacitive screen. According to the different demands of users, our company has successfully developed the JKL5C, JKW58, RRCF, JKW9F, and JKW5C types of intelligent controllers. Number of the channels controlled is 4, 6, 8, 10 or 12.

All of our products are controlled by the microcomputer. With the advanced technology, they have a complete range of functions, strong anti-interference ability, stable and reliable running, accurate compensation, and novel appearance, so they are the preferred products for capacitive screen manufacturers.

Main Function
Our reactive power compensation controller can be used in electronic power supply system for increasing the power factor of grid, reducing loss of supply transformer and transmission line, enhancing power supply efficiency and improving power supply environment.

Main Characteristics
1. By state-of-the-art single-chip microcomputer technology, fully automatic SMT and advanced test equipment, our reactive power compensation controller features high precision and high sensitivity.
2. This type of reactive power compensator in line with the standard of DL/T597-1996 is suitable for the automatic control of capacitor compensation device in the low voltage power distribution system. It can enhance power factor up to what the users require, improve the utilization efficiency of power transformer, reduce line loss and improve voltage quality, thus boosting economic and social benefits
