Intelligent reactive power compensation controller is new generation product, to meet development requirements of automatic reactive power compensation.It is used with our intelligent capacitor, with simple wiring , reliable running characteristics.etc. It can real-time show the RS485 interface, power factor, voltage, current, reactive power and other electrical parameters, and intelligent capacitor sets and cutting state, make it very simple, at the same time can save a lot of wiring.
二、Main fuction.
1.CONTROL FUCTION.
（1）Auto,manual control
（2）Automatic switching on-off control be carried according to the controlled parameters (power factor, reactive power, power distribution, current, voltage)
（3）Same volume capacitor based on the principles of cycle to switch on-off control, different volume capacitor control base on reactive power gaps.
（4）predict switching distribution reactive compensation before switching, if it as predicting, and need opposite practicing, then no switching, it can prevent oscillation;
2.Fuction setting
（1）transformation ratio setting
（2）Delay time setting
（3）The power factor setting
（4）protection setting value setting
3.Measurement fuction.
Distribution voltage, current, power factor, reactive power measurement
4.Communications functions
Capacitor operation, return status and way;
5.Protection function
（1）Overvoltage, undervoltage, and loss of pressure protection;
（2）Oscillation protection
