Single-Phase Automatic Voltage Regulator（AVR）

Single-phase automatic voltage regulator is a device used to adjust the voltage of single-phase AC power, mainly composed of single-phase auto-coupling voltage regulator, on-load tap changer, automatic controller, etc. It can adjust the input unqualified voltage to a stable and qualified output voltage to meet the voltage demand of the load. It is mainly used in power systems. Industrial production and other of the fields. It is widely used in the Middle East，America and Australia，and the product is mature and reliable.

Overview

Single-phase automatic voltage regulator is a device used to adjust the voltage of single-phase AC power, mainly composed of single-phase auto-coupling voltage regulator, on-load tap changer, automatic controller, etc. It can adjust the input unqualified voltage to a stable and qualified output voltage to meet the voltage demand of the load. It is mainly used in power systems. Industrial production and other of the fields. It is widely used in the Middle East，America and Australia，and the product is mature and reliable.

Configuration & working principle

The Single-phase automatic voltage regulator can automatically track the output voltage of the voltage regulator. When the output voltage is detected to be out of limit, the tap changer is automatically controlled to smoothly adjust the tap changer gear position, so that the output voltage is kept within the qualified range.

Features

1. High precision:within the set voltage regulator range, there are 32 levels of automatic voltage regulation on load;
2. Long life:unique voltage tap design avoids arcing during voltage regulation, and can guarantee a mechanical operation life of 1 million times;
3. Maintenance-free:fully sealed design, high protection level, excellent weather resistance, long-term maintenance-free, and a design life of 20 years;
4. Low loss:single-phase design can minimize iron loss and reduce no-load loss, with a total loss of less than 0.1%
5. Strong overload:rated capacity is designed is according to 55℃ temperature rise, and can be overloaded by 12% at 65℃ temperature rise.
