Application

Full digital design, AC sampling, human machine interface is large LCD display.

Designed with friendly human care, module asse-mbly,flow-line figure

It can display power factor, voltage, current, active power, reactive power, distortion rate of total voltage harmonic waves, distortion rate of total current har-monic waves, frequency average value, and capacitor switching status and etc for A, B, C, phases. 

Parameter setting, to be instructed in Chinese words and English, digit input.

Capacitor control modes, three kinds: three-phase compensated together, the phase respective com-pensation, combined compensation, you can set the control modes through the menu

Switching program has the equal capacity/coding (1:2、1:2:3、1:2:4:8…) and fuzzy control modes.

Two working modes: Hand compensation/Auto

Compensation

Parameter sampled is reactive power, it has thefunction of measuring harmonics and protections.

The controller provides RS-485, MODBUS standard local bus and comm.. port, used to connect with intelligent switchgear system.
