The Ability Power AVR can be used safely with any computer system, fax and photocopy machines in industrial, medical, laboratory, office appliances and household situations.

The Ability Power AVR protects your load from all fluctuations in the mains voltage and carries out voltage regulation. It cuts the voltage outputs electro-mechanically when an increase or decrease occurs which is out of limits and prevents all mains supply variation problems by electronic protection.

The booster transformers and sensitive variac are the main components to complete the voltage regulation. A servo system is based on the control of a DC motor by a thyristor.

Output voltage can be observed from the equipment’s analogue display. Over current protection is made by a magnetic switch and the system is fan cooled. Single-phase models are naturally cooled. Connection to the unit is by NK model Clemens.

Phase protection, which is operated optionally, cuts the low or high input voltage, and if there is a phase failure, cuts the output voltage using a contactor. In order to avoid the possible problems that can be caused by sudden voltage fluctuations, the Ability Power AVR includes a time relay, which can take the control in 2 seconds. It has a by-pass switch and on/off facility.
