AUTOMATIC VOLTAGE REGULATION

PROVIDES STABLE OUTPUT VOLTAGE UNDER ADVERSE LINE CONDITIONS

About Torus Power AVR (Automatic Voltage Regulation)

voltage-regulationThe Torus Power AVR is a full-feature state-of-the-art power transformer, isolating and protecting your system. Like all Torus Power products, the AVR series provides true isolation (using massive toroidal transformers) and protects all connected equipment from the risk of severe power line surges using series-mode surge suppression.

In addition, Torus AVR provides stable voltage to keep equipment running in the optimal range of 115VAC to 125VAC for any input voltage from 90V to 130VAC. (International units operate within nominal input voltage such as 220V, 230V, 240V; Torus AVR keeps them operating within a range of +/- 10V.)

Torus Power AVR technology uses a micro-processor to monitor and control the voltage, seamlessly switching the multi-tapped toroidal transformer to the correct setting. The front panel display on the Torus Power AVR indicates input and output voltages, displays output current, as well as displaying fault conditions.

AVR supplies Optimum Input Voltage over a Wide Range of Adverse Line Conditions

Following are the range of operating input voltage conditions specified for Torus products to maintain optimum input voltage to your equipment.

  • North American models (15A, 20A): Torus AVR will keep the output constant within the range of 115 Volts to 125Volts, with an input voltage of 90V to 130V. Between 85V to 90V, and between 130V and 135V, the regulation will be reduced.
  • North American BAL models: Torus AVR will keep the output constant within the range of 115 Volts to 125Volts, with an input voltage of 170V to 270V. Between 160V to 170V, and between 260V and 270V, the regulation will be reduced.
  • International models: Torus AVR will keep the output constant within the range of 240 ± 10Volts, with an input voltage of 170V to 270V. Between 160V to 170V, and between 260V and 270V, the regulation will be reduced.

Why your system needs automatic voltage regulation

Under ideal conditions, when the supplied power line is stable and dependable, you may not need voltage regulation. In such an ideal situation, your equipment can operate within the normal tolerance of the line voltage. In reality, the power supplied to most areas is less than ideal due to outdated power grids. In most areas, the power regularly drops or rises beyond the acceptable range (in North America +/– 5V, Europe/Asia/Australia +/- 10V).

These voltage sags, brownouts, and surges can stress components and shorten equipment life. In the worst case, catastrophic events can destroy valuable equipment. In such real-world conditions, the Torus Power AVR can protect your equipment, and improve the quality and enjoyment of your audio and video experience.

Torus Automatic Voltage Regulation technology provides stable voltage to keep equipment running in the optimal range of 115VAC to 125VAC (North America), and +/- 10V on international voltage ranges such as 220V, 230V, 240V. The Torus Power AVR is pre-programmed to power down the system when a high or low fault condition occurs (with user over-ride available).
