The APS – AVR 3P Voltage Regulator is a server drive structured microcontroller for heavy-duty devices. It regulates critical load voltage. The APS AVR consists of a Servo Controlled Injection circuit that supplies an in-phase or out-of-phase voltage to the primary of a buck/boost transformer, its secondary winding is connected between the supply and the load. The injection circuit can thus add or subtract a voltage to the supply.
The microprocessor monitors the output voltage of the stabiliser and controls the supply of voltage to the injection circuit. The servo mechanical circuit coupled to the buck-boost transformer is energised in the appropriate polarity to restore the voltage to the correct level. The method of stabilisation inherently compensates for any change in the output voltage. By adopting this methodology, the APS-3P ensures that loads are not subjected to voltage variations which either are too low or too high, which result in equipment failure such as electronic control systems failing or burning out due to over voltage or motors and cooling systems stalling and failing due to very low voltages as a result of not enough torque. The APSAVR 3P is designed to operate 24/7 continuously in harsh environments to protect and ensure the long life of the equipment. This technology incorporates simple-to-read displays to ensure clarity of raw power and regulated power from the AVR itself.
