Automatic Voltage Regulators (AVRs)
A voltage regulator is designed to automatically maintain a constant voltage level. Depending on the design, it may be used to regulate one or more AC or DC voltages.
The AVR is a state of the art solid state stabiliser. Using microprocessor technology, the AVR will rapidly detect voltage variations and correct the output to ensure 230V (+/-4%) supply. The AVR has a very wide input range (-30% to +22%) and a voltage correction speed of 1250Volts per second. No mechanical parts means that the AVR doesn’t require maintenance and will not be affected by dusty environments as other mechanical (for example Servo type) stabilisers.
The three phase AVR is made of three identical single phase regulator units providing independent control. The three phase range boasts the same standard features with one of the widest ranges as standard in the industry. A number of options are available, making the three phase range a very comprehensive source of secure, stable power.
