AVR (Automatic Voltage Regulator)

AVR is a device that regulates the amount of voltage needed for a certain equipment which generates, monitors, and analyzes power for a more suitable and reliable power for computer/equipments. Capable of:

1. sense over voltage and under voltage of the input line.
2. sense over current in the load.
3. sense aberrations in the power lines such as: - intolerable spikes transients - surges and sags - slow average fluctuations
4. maintains the output voltage within its tolerance ( + 1%) of the nominal voltage
5. responds/recover to input variations within one (1) cycle or 0.16 seconds, usually termed as the response time.

Optional:

Audio/visual monitors or warnings

Cut off power when such aberrations occur protecting the circuit itself and

the computer or equipment.

Delay time

Types of AVR 1. Mechanical AVR

– incorporates electro-mechanical parts such as relays and motors – slow response time in terms of seconds – requires maintenance – heavy 2. Electronic AVR

– uses semiconductor parts in regulating voltages – quick response time in terms of milliseconds – no maintenance requirelight in weight – light in weight
