Projector Power Supplies 5 for $18 Free Shipping US

[DTR]

Ok so I need to clear out some of these power supplies that have been stacking up. They are $18 for five supplies with free shipping in the US.

Power supply has three outputs. A low current 5V line, A high current 10A+ 4.2V output and a 10A+ 12V output.

The power supply will always provide 5V on the low current 5V output so long as it is plugged in. This line is used to toggle on and off control of the 4.2V or 12V outputs. Jumping the pin labeled below "power on" with the pin labeled 4.2V will turn on the 4.2V ouput or jump it with the pin labeled 12V below and it will turn on the 12V output.

Little update.

I am getting 10.5A on the 4.2V.

First I tried powering a flexdrive set to 1450mA. No issues.

Then I did an Amp test and it was reading 10.5A but that is the max rating on my DMM so it may be capable of much more.

Also tried my Red LED from the projector and it works perfectly from the 4.2V output.

Sry to ask if its been posted but got a pinout or spec sheet?

Re: Projector Power Supplies

Did you figure out how to make these give out any power?

Peace,

Re: Projector Power Supplies

I know there was a thread over @ PL on them but I am not sure if they got anywhere.:thinking:

I will try to dig up the link.

Re: Projector Power Supplies

i wish these things would give out a +24 and -24 along with a 5V line.
Use this in my laser projector

^^^Here is some information but I don't know if his tests were completely successful in fooling the power supply that the LD array is there. Anyone here had a chance to get one working?

Ok, I took a pic of the where my test leads are.

Then I tried a jumper between the first pin and the 3rd pin pins 3 & 4 are the same.
This resulted in a fluctuating voltage at 12 to 12.5

Then jumping pin 1 to either pin 5 or 6 results in a fluctuating voltage from 4 to 4.5

If any one with better testing tools can see if these yield a good voltage please test this out. I only have this DVM.

And some more good info.

I've been studying the power supply as well. Here's the pin-out as far as I've derived:

I believe the Power ON to the 6-pin connector is an input, and the one on the 16-pin supply is an output, as the former is the input to a photocoupler, and the latter appears to be connected to the collector of a transistor (?) Q102.

The +5V is always on as far as I can see, and is used to turn on the power supply through the photocoupler-connected lead. The power supply might be be providing 12V as well, or just staying on because the power on is floating. I'll have to test it later when I splice the cables.

Edit:

Power ON on the 6-pin connector is active-low. You're measuring 4.53V because of the diode in the photocoupler and the resistor in-line. The anode (+) is connected directly to the +5V input on the 6-pin connector.

Re: Projector Power Supplies

Very interesting !

Do you ship to Greece ?
Can you tell me the dimensions?

 

[DTR]

Re: Projector Power Supplies

^^^I can. For the 3 quantity add $10 or I could do 15 for $95 shipped to Greece First class in a medium flat rate box.:beer:

Re: Projector Power Supplies

For how long will you be selling these ?

Re: Projector Power Supplies

I have about 70 on hand and I will have them till they run out.:beer:

Re: Projector Power Supplies

I'll see if I can verify the pins above on the one I have here later tonight.

Thanks.:beer:

Have you been able to get it to power anything?

Re: Projector Power Supplies

Hmm those wouldn't happen to be xbox 360 power supplies would they?

From a quick google image search I would say no.

Re: Projector Power Supplies

Well from what I seen on an image search and in real life there seems to be many many different versions of the board layout on the power supply. That board is the correct shape and very similar in parts and construction (for example I noticed there is a dark grey epoxy identical to what I found on one I took apart..) has the same power outputs and even has that one wide ic just like one I took apart did.

Im nearly 100% confident that is an xbox 360 psu.

Re: Projector Power Supplies

These are from the c@sio projectors.... They are used to power the laser array apparently.
