Need a Power Supply for a Proxima Ovation 822c

[Flay]

Any ideas?

I just won one on Ebay for a cheap price, but it needs the power supply. Does anyone else have this model?

Thanks in advance.

you might can find a perfect fit plug with variable voltage and +/- polarity switching at radioshack.

I don't think so.

The Infocus panel uses a 5 pin din connection like on old keyboards.

I called Infocus technical support and they couldn't help me. They refered me to a store out in CAlifornia that wants $150 for the power supply!

I just wish I knew how to make my own. Can anyone help me?

You're probably going to have to do a custom job. Here's a similar thread where they were finding a power supply for an NView.

Here's the best page I've ever found for wall transformers:

Hope this helps you.

Pinout

Here's the pinout for the power supply. Grab a spare PC power supply. Should have the required outputs. The plug is the same as an AT keyboard connector ( 5 Pin DIN?) . Radio shack carries them. Have fun.

Thanks HanClinto and Bixs. I actually have the 5 pin din from an old keyboard. And I can lay my hands on an old power supply.

Do I have to make/buy an adaptor to connect the 5 pin din to the power supply or are you talking about soldering connections from the power supply to the wires of the 5 pin din?

If so, is it easy to figure out which cables from the power supply need to be soldered onto the wires for the 5 pin din?

Also, are the input requirements for the panel, (100 - 250 V, 50-60 Hz, 1.2A), normal for the average ATX power supply?

Thanks again for your help.

I am using a radio shack 13.5V 1000ma for my sharp qa-1650. The required adapter is a 12v 1.95A. I'm using almost half the amp, It works but do you think it will harm the thing after awhile?

I would use an AT power supply that way you can turn it off with the switch. I tried using an old keyboard cable but it didn't work. Panel draws to much juice and the cable got hot pretty quick. You can get the connector from radio shack and then solder the wires from the power supply to the correct pins. Most power supplies have a diagram showing which wire carry what voltage. The power supply should have no trouble powering the panel.

yeah but i'm thinking he might be worried about overpowering the panel

Overpowering the panel?

Correct me if I,m wrong, but shouldn't the panel only draw the current that it needs? It shouldn't matter if the power supply is capable producing more amps than the panel requires.
