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 ,12 and 14 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

 

 

Function features

 

1. On basis of 3 phases fundamental wave reactive power, calculate the reactive power to be switched on, it can avoid switching shock of any forms, it can accurately display the power factor of system

with harmonic wave.

 

2. High measurement accuracy, wide display scope

 

3. Real time display general power factor and fundamental wave PF

 

4. Real time respectively display 3 phases voltage, current, active power, reactive power, apparent power

 

5. Total 12 kinds of coding output can be chosen

 

6.kinds of schedules can be chosen by user (distribution the circuit nos of corporate compensation, or respective compensation)

 

 

7. 16 circuits of output at maximum

 

8. Human friendly interface, convenient operation

 

9. Various control setting can be adjusted digitally, directly and easily.

 

10. Automatic and manual operations, two modes provided..

 

11. Over voltage and absent voltage protection provided.

 

12. Data not lost even if power shut down.

 

13. Current signal input resistance ≤0.01Ω

 

14. Compensating power factor able to be adjusted:0.70 lag~0.7 forward.
