KI-DAVR-50S 5KW Automatic Voltage Regulator
The KI-DAVR-50S 5KW Automatic Voltage Regulator (part KI-DAVR-50S) controls the alternator's excitation so the output voltage stays steady as the load changes. Rated for alternators up to about 5 kW.
About this part
An AVR senses the alternator's output voltage and adjusts the current in the exciter field many times a second to hold it at the set point. Without it, voltage swings with every change in load and can damage connected equipment.
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
Set the voltage and stability adjustments with the generator off load first, then check the response with a load applied.
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
Will a universal AVR work on my alternator?
Often, if the sensing, excitation current and supply voltage suit. Send us the alternator make and model and the old AVR number and we will confirm.
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.
