AVR - Automatic Voltage Regulator GAVR-35A
The AVR GAVR-35A (also known as NEW POW50A) is an automatic voltage regulator, easy to wire, designed for 2 -wire brushless single-phase generators. Offers exceptional voltage regulation of less than +/- 1% (with 4% of the nameplate engine power) and features a soft-start voltage build-up to protect your equipment. It allows detection of 120 or 240 V CA, selectable by jumper, with a detection/power range of 90-140 V CA. Its output is powerful, with a maximum voltage of 100 V CC at 207 V CA input and a continuous current of 35 A. In addition, it includes frequency-drop protection with an LED indicator for greater safety.
AVR - GAVR-35A is the automatic voltage regulator of the generator: it reads the output voltage and corrects the field excitation so the voltage stays stable as the load changes.
A failing AVR shows up before it dies: voltage dips 5–30 V when a large motor starts, lights flicker, or the control panel reboots. When it fails completely the set delivers only residual voltage or trips on overvoltage.

How to verify before ordering
- Check that the reference printed on the AVR label (for example AS440, MX341, R120) matches exactly; variants differ in sensing range and excitation level.
- Confirm the excitation input voltage and the generator type it serves. They are not interchangeable across generator makes or speed ranges.
- Inspect wiring and brushes before replacing the module: a loose connection produces exactly the same symptoms as a burnt AVR.
Frequently asked questions
How do I know the fault is the AVR and not the generator?
Measure output voltage at steady load. If it is low and does not respond to the excitation trim, while windings and rotating diodes are healthy, the AVR is the suspect. A cross-test with a spare AVR confirms it in minutes.
Can the voltage be trimmed after installation?
Yes. Most of these regulators have a voltage and a stability trim pot. Set them at no load to the site nominal voltage, then verify under load before signing off.
