In a previous video I showed some images that AvE had been sent by someone who’s power supply went on fire while they were out of their house. (The neighbours heard the smoke detector and intervened.)
This is a similar power supply I bought to test with a high load and check out the circuitry.
I may go a bit deeper and test isolation at a later date, although that may involve destroying the power supply. I couldn’t say if this particular power supply is an identical one to the unit that went on fire, as it may be from the same factory or maybe just one of many clones.
My tests did show a weakness that may have caused the fire though. The good news is that it’s easily addressed.
Note that I’d not rate the current limiting function as being usable as a proper constant current supply as it is too unstable. It’s better regarded as being an upper safety limit.
