Dangerous UPS componants

[Cannibal23]

hello all

just a little question and hopefully someone here knows the correct answer. basicly what im looking to know is what componants are not safe to touch inside of a ups after AC power and DC power are disconnected. i have heard that still some componants retain enough juice to seriously make your day .... well unplesent. was hoping to avoid them but i wont be able to do that if i dont know what parts. transformer? capacitor? what do i avoid touching at all costs?

As far as I know the capacitors are the only dangerous things, they can be discharged by shorting the poles with something like a screwdriver. Just be careful!!

Agreed, capacitors are the killers. As for shorting them with a screwdriver, I wouldnt do that. That's just me.

If in doubt, call your local TV repair shop; they can likely discharge the components for you.

ok so i will dodge the caps in there... especially the huge blue ones..... shudder... im not planning on really touching any of the solder points on any of this stuff. just want to remove some of the boards temporaraly to do some work inside and dont feel like getting zapped. so i dont have to worry about a transformer inside there? i know there is one its huge but they dont hold any juice right?

Shouldn't and you can discharge the capacitors if you want. They should be rated for 12v. You should be able to put a light bulb on it to drain it if you are concerned. When I bought a 1 farad cap for my car stereo, it came with a light bulb to drain the cap.

awesome, thanks for the advice guys. trying to see what i can do to my ups to make it a little more presentable.

Cool. Don't forget pictures.

The duh light just went off. I don't know why I never thought of that. +rep

**EDIT**
I should mention that doing any of this is at your own risk.

i wont forget dude. have to come up with a doable design idea first. there are some physical interfearances preventing me from doing exactly what i would like. beyond that i cant find my darn multimeter so i can start looking for voltages that i want to use.

We all have our moments.

What kind of PSU is it? And what is your exact idea? Maybe we can throw some options or other ideas your way
