This is a 13.8v 20Amp power supply. I was using it to charge a few LiPo batteries for a RC car. I noticed there was a burnt smell coming out of the rear end. The fan was working fine, so I checked that. I did not overload it because this charger will do 4 batteries at 50watts each. So 200watt capability in total. The power supply is rated at 270 watts. At the time of this incident I was charging only 2 batteries.
On a side note, the fan was working at a very low speed. I don't know if this matters.
Turned it off, opened it up and used an infrared temp probe to see what was burning. It turns out the copper coiled up thing showed in the picture was at 250 F. What does that part do, is it supposed to get hot? Capacitors and other parts were around 110F. Any help would be appreciated. Thanks.
