GB-130 Brush Automatic Voltage Regulator
If the voltage from your generator is hunting, too high or collapsing, the AVR is the first part to check. GB-130 is a replacement regulator.
About this part
Sensitive loads such as computers, inverters and motor drives depend on a steady voltage. The regulator is a small, inexpensive board that protects everything downstream of the generator.
Features
- < +/- 1% RMS with 4% engine governing
When to replace it
- Output voltage that is too high, too low or unstable
- No output voltage although the engine runs normally
- Lights flickering or voltage dipping as loads switch on
- A burnt or damaged board after a lightning strike or short
Before you order
Match the AVR to the alternator: sensing (single or three phase), excitation type (brushless or brush type), supply voltage and the physical mounting all have to suit. Note the wiring before disconnecting the old regulator.
If the old part has no readable number, send us a clear photo with the engine or alternator nameplate and we will identify it before you buy.
Questions
What is an "alternative" AVR?
A regulator made to replace the original part on a specific alternator brand, at a lower cost than the brand part.
Why did my AVR fail?
Common causes are overloading, a short on the output, a failed rotating diode or a surge. Check the rectifier diodes before fitting a new regulator.
