Triol Voltage Compensator KH24 is designed to improve the supply voltage and provides unstoppable voltage supply to eliminate dips in three-phase voltage curves. KH24 has a forceful power part based on IGBT-converters. KH24 range of output voltage is 380V, 480V, 690V.

  • reliable and continuous power supply in case of emergency and abnormal conditions in electrical networks;
  • elimination of phase asymmetry in the standard power mode;
  • voltage maintenance of the on the load for 1 second in the absence of input voltage, which allows guaranteed transfer to the backup power line.
