IGBT controlled Static Voltage Stabilizer
WORKING
Encon QUIKorrect , IGBT based PWM type static voltage stabilizer only the difference voltage is switched through IGBT and will be added or subtracted from the mains. This is done electronically without any step changing in voltage which occurs when the system regulates. This is achieved by a feedback control system using digital signal processor (DSP). The output voltage is sensed by the DSP and corrections are made by varying the duty cycle of the PWM at 20KHZ and correction speed 20000/second.
This stabilizer boosts up the voltage if it is low and bucks the voltage if it is high.
Highlights of QUIKorrect:
* Instantaneous correction speed – over 20000V/second
* Discrete IGBT up to 30KVA 1PH and 90KVA 3PH
Module IGBT up to 70KVA 1PH and 210KVA 3PH
* Single PCB for control stage, IGBT driver section and power stage
* RFI, EMI and Surge Protector inbuilt
* Single contactor for three phase system
* Single LCD for three phases
* RS 485/Bluetooth connectivity
* Output Voltage Regulation – +/- 1%
* Automatic Bypass
* All protections included – low voltage, high voltage, overload, short circuit over temperature, phase reverse and phase fail
