Description
The lower limit of −59 % means that the unit holds the output even when the mains is below half of nominal, while ordinary ±20 % stabilizers would have switched off long ago. Regulation is done by thyristors under microprocessor control; there are no moving contacts or brushes in the circuit. The correction speed is 1250 V/s, so surges and sags are handled within a fraction of a second, and the base-station equipment does not notice them. An accuracy of ±4 % at the output suits telecom power rectifiers and equipment-room air conditioners. The cabinet stands on wheels, and digital measuring instruments are placed on the front panel.
How to choose
The AVR-W makes sense where the voltage regularly drops lower than standard models can withstand. If the deviations stay within ±20 %, the AVR-L (AVR3LS) at 70–140 kVA with 3 % accuracy is enough, and at ±30 % the thyristor AVR3AE from the Pro series. The power of the AVR-W is clarified with the manufacturer for the load of a specific site.

FAQ
What is the input voltage range of the AVR-W stabilizer?
The AVR-W works with a deviation from −59 to +36 % of nominal and holds the 220 V output with ±4 % accuracy.
How fast does the AVR-W correct the voltage?
The correction speed is 1250 V/s. Regulation is thyristor-based with microprocessor control, without mechanical elements.
How does the AVR-W differ from the AVR-L?
The AVR-L is designed for a ±20 % input and gives 3 % accuracy, while the AVR-W accepts −59 to +36 % at the cost of a wider ±4 % tolerance at the output.
For which sites is the AVR-W stabilizer intended?
For telecom sites in areas with extremely low mains voltage, where ordinary stabilizers switch the load off for long periods. If the mains rarely goes outside ±20 %, the simpler AVR-L with 3 % accuracy is enough.
