I noticed some of them include a simple light, which slowly gets dimmer after disconnecting the power. Is it to discharge that capacitors?

Is it to discharge that capacitors?
- exmadscientist 5y agoThat's discharge + indication all in one. It's a great solution, elegant, effective, and one of my favorites. But you have to find the cents for the neon (usually) bulb.
- jlgaddis 5y agoBe careful, that's (probably) just on the DC side...
- Scoundreller 5y agoIsn’t the AC side connected to the wall prongs? I touch/step on those all the time after unplugging things. Or is there something isolated from both the DC side and prongs where charge could be stored up?
- garaetjjte 5y agoYes, there's bridge rectifier.
- bonzini 5y agoThose big-ass black capacitors (470 uF each) are on the AC side. They are the bit that converts 230AC to 320DC, and they might keep their charge for some time.
- SAI_Peregrinus 5y agoThose are after the bridge rectifier, so there's no path for current to flow back out the plug from them. That also means you can't discharge them via the plug, of course.
