12 VDC from TigerPro Power Supply

12 VDC from TigerPro Power Supply

I have a TigerPro Model TP-450 power supply. I want to use the 12 VDC output for another project. What do I have to do to get it to work stand alone?

RE: 12 VDC from TigerPro Power Supply

There were some articles in QST magazine in the past year, about adapting computer-type switching power supplies for use powering things other than computers. The details are too long to post here, but it is doable. I'll try to check my back issues of QST, or an ARRL Handbook for Radio Communications, to find a reference for you.

RE: 12 VDC from TigerPro Power Supply

Thanks for your inputs. I searched for "computer power supply schematic" and found a site that had design info for a similar supply. From this I concluded that connecting the green wire to common (black wire) would turn it on. It worked. I also found a place that says you should put a load on the +5. I haven't tried that yet.

RE: 12 VDC from TigerPro Power Supply

The QST articles talk about the minimum load on the various outputs and such. Good luck!
