Function and Feature

  1. Display Function

* The LCD display, showing up to 30 intelligent integrated capacitors status, can display various operating parameters and setting parameters.

* Touch key control is elegant and beautiful.

2.  Parameter Setting Function

* Setting various protection value: overvoltage protection, overvoltage lockout and undervoltage protection.

* Setting various switching limit: delay time, input and cut-off threshold quantity.

* Setting the ration of sampling current transformer.

3.  Measuring Function

* The polarity of the sampling transformer is automatically determined. No polarity requirement when accessing.

* Distribution voltage, current, power factor, active power and reactive power measurement.

4.  Control Function

* Automatic and manual control of capacitor switching. When in automatic control, the switching is performed according to the controlled physical quantity-reactive power.

* For capacitors with the same capacity, the switching control system is circulatory. The switching control system of capacitors with different capacities is coding control in accordance with the reactive power shortage.

* Simultaneously control up t 30 intelligent integrated power capacitors.

5.  Protection Function

* Harmonic protection, overvoltage protection, overvoltage lockout, undervoltage protection, open-phase protection and undercurrent protection.

6.  Signal Function

* Displaying the operation and stop signal of each capacitor, and its capacity signal.

* Displaying the over-limit signal of distribution parameters (overvoltage, undervoltage and undercurrent, etc.).

* Displaying the fault signal of controller itself or capacitor.
