Jkwh series reactive power automatic compensation controller adopts LCD large screen LCD, operation data one screen display, analog power factor mechanical table, showing the humanized design of equipment, accurate measurement and control program, 21 channel compensation control interface, providing better help for users’ fine reactive power compensation and saving.

 

Jkwh series, using large-screen LCD, pure Chinese interface, It had already passed high and low temperature aging test, vibration test, drop test and anti-electromagnetic interference testing.

It can display real-time measurement of three-phase voltage, current, active power, reactive power, power factor and active energy, etc.

It also has some functions such as: over-voltage, low-voltage, loss of pressure, phase loss, over-current, low-current, power-off protection. With RS485 and RS232 communication interfaces and PC software.

 

Jkwh series intelligent type reactive compensation controller as a new generation, integrate the functions of data acquisition, reactive power compensation, analysis of system parameters and etc, suitable for operating in the distribution system of AC0.4KV, 50Hz to monitor and control reactive compensation.

 

Jkwh series intelligent type reactive compensation controller adopted hi-speed digital signal processor, execute AC sampling. HMI is matrix 128×64 LCD, provided with supervision, reactive compensation, harmonic analysis, and adaptive freq calculation, the input signal change within 45Hz~55Hz
