Hi! I have purchased for a cheap (20euros) a power supply made by unknown brand. The unit has a 1 analog instrument which shows voltage/current. So the main question is why does my psu behave like shown in a video? I mean, why voltage jumps to the max. value during the powering the unit off? https://easyupload.io/g4favk Thank you and sorry for shaky video. Hrvoje |

No video, just a bunch of Ads and a link to some dodgy software. Try YouTube or Odysee. Ian. |

There may be stored some energy in a capacitor. Try to put a load on it, e.g. an 1k resistor. Photos of the inside may help understanding how it works. |
