Thyristor Type

Single And Three Phase Up to 100 KVA

SCR Type Voltage Stabilizer is top line of Voltage Stabilizers, Replacing mechanical switches with semiconductor AC Switches (TRIACs) offering a TRUE STATIC Regulation at high speed correction rate. The system consist of multi-tap auto Transformer, Power TRIAC circuit, Microcontroller based control circuit and LCD display circuit. When the voltage fluctuates or the load varies, automatic measurement/control circuit will send signal to Fire the selected TRIAC, then the output voltage will be adjusted to rated value and get a steady state.

SCR Type Stabilizers: offers the best regulation for sensitive single and three phase loads using a rigid design using a microcontroller controlling a multi-tap auto-transformer being switched by TRIACs. The system is carefully designed with with overrated components to ensure smooth and reliable operation benefiting the existence of a microcontroller to offer a rich set of protection and intuitive user interface.


  • Single and three phase units designed for heavy duty industrial working conditions.
  • Independent phase regulation to correct voltage and load unbalance.
  • Control and stabilization are performed on the true RMS value based on digital
  • microprocessor operating with a software specifically developed.
  • Wide input range 380±15%or380±25%(other on request).
  • High quality components are used to provide optimal voltage regulation.
  • Protection against overload, high voltage, under voltage and other failures.
  • Interactive user interface that monitors each phase independently and displays
  • operational status by means of LCD and colored LEDs.
  • High efficiency up to 98%.
  • Integrated manual rotary maintenance bypass witch standard on all units.
  • Long life and maintenance free performance.
