Default what is this thing??

Hi all, well I picked this thing up at a garage sale for 50c couldn't leave it sitting there for that price but now im left scratching my head as to what exactly it is and what is its real intended use, any help would be greatly appreciated.

The two little black knobs on the side seem to be used for pinching two wires im assuming for a temperate connection?
and then theres the black box with the circuit board and the wires that run inside the unit??

it looks like a homemade power supply. Maybe for low voltage lighting, or some other shop use. If you put a volt meter on the two black lugs you'll probably find 6-24 volts.


I made one many years ago when the battery in my old zenith laptop died. Mine puts out 4- 36 vDC.

Old transformers and a handful of diodes can come in pretty handy....

yeah thats what i am getting its putting out like 5.8 bouncing around that number from the two plugs and 119volt from the main plugin, so what are the lugs for? and what is the circuit board intended to do?

I guess my main question is can i use it just like a regular extension cord? cause the reason I bought it was to plug in things like my router when its mounted in the table so I can just lock the button on and control the on/off from this thing.

Paul,

The lugs are the output to whatever device he was powering. unscrew one, stick a wire under it, clamp it back down... simple but effective.

The circuit board is probably a step down transformer and rectifier, and it might get a little warm if you have the unit plugged in for a long time, but probably not any sort of hazarrd.

I would pull the switch and receptacle out of that box and put it in a single gang box. If you use a grey surface mount conduit box you can get something easy to mount and something that looks a little more 'finished' than cobbled together.

Still a good deal for a switch and receptacle @ $0.50

Not sure by pic. Id guess a power supply for a tattoo machine, that had a foot switch. I use to be a tattoo artist and it looks similar to one I made. When necassary I could power a machine off my Harley battery.

I agree with the apparent consensus of a low voltage power supply. I would guess to provide power for an electric train transformer and also a lumpy DC output for scenery lighting. As far as using it as a remote switch for a router, the power cord feeding the thing looks a tad light duty to me. JMHO

The problem with experience is I usually get it immediately after I need it.
