10 Wire AVR Voltage Regulator



AVR Voltage Regulator at Generator Parts World

This is a 10 Wire AVR Voltage Regulator

This is a universal type voltage regulator, also called an AVR. This voltage regulator is intended for use in 4Kw to 12Kw single phase generator applications.

This AVR voltage regulator has 3 plastic plugs and 2 single wire female connections. This AVR is a single phase type of AVR that is most commonly found in diesel generators. This doesn’t limit this part to diesel generators, that is just where they are most commonly found.

If your generator stops producing power the AVR is one of the most common issues. First check that your carbon brush assembly is making contact. If the brush is making contact visually inspect your AVR for burnt spots or blown capacitors.

If your voltage regulator is defective this may not be your only issue. An AVR should last for at least 2000 hours in any generator. If your AVR does not have this much time used then you may have another issue. Even if your generator has over 2000 hours you may have an issue that caused the AVR to fail. We suggest properly testing the generator prior to purchasing a new AVR or you can use the AVR as a test to see if that is the only issue. The most common other issue is moisture or debris in the head, causing current to jump. Any replacement AVR may need to be adjusted when replacing.
