Reliable power for a sustainable world
Also known as an Automatic Voltage Regulator (AVR) or Voltage Regulator (VR), an Automatic Voltage Stabiliser (AVS) stabilises the mains power supply voltage to a load.
It is a feature of Line Interactive uninterruptible power supplies and provides protection from power problems such as sags, brownouts and surges.
Automatic Voltage Stabilisers have a wide input voltage window (+20/-40%). If the input supply voltage is too low, the AVS uses a transformer to boost (step-up) the output voltage. On the other hand, if the input supply voltage is too high, the AVS reduces the voltage to a safe operating range (this process is known as buck or step-down).
