How to adjust AVR ?

1370 Views 6 Replies 4 Participants Last post by  iowagold
My AVR has two adjustment screws, can anyone tell me why two? Is there one for each 110v winding?

What's the correct procedure for adjusting the AVR and is 220 v the correct voltage or can i go to 240 v which some of my power tools state is their input.

I just replaced the AVR and im getting 100 v from each winding.

What is your model?

The AVR model is KI-DAVR-50S and it's for a Kipor genset.

The pot nearest the edge adjusts the output voltage. This is self-exaplanatory.

The other pot (near the capacitor) adjusts the "overload" status condition, which is indicated by the LED. The way I understood it is that you fully-load the generator to capacity then adjust the pot to the left (CCW) until just before the LED lights up. So if the load goes above 100% (or whatever you set), I imagine that the AVR goes into overload and cuts power to the exciter and consequently, cuts power to the output. This is just an educated guess.

Can a welding transformer be used as a 5 kw load bank to set the overload protection ?

Welding is not my field of expertise. For as long as you can present a steady and known-quantity load to the generator, you should be able to dial in the overload setting. Popular choice is to use several space heaters as a load bank. They have a power factor of 1 (resistive) so you know that the kVA and kW are the same.

^ I would second that. The power factor can throw you for a loop and you won't really know where the gen overload is set.
resistance load bank is the best way.
