What Does An Automatic Voltage Stabiliser Do?
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).
