KI-DAVR-50S3 3KW Automatic Voltage Regulator
KIDAVR50S3 is an automatic voltage regulator (AVR) for generator alternators for Kipor alternators. Rated for alternators up to about 3 kW.
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.
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.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
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.
