HP 6268A power supply small transformer need

Post by al » Sun Nov 10, 2002 11:56 pm

i need the small transformer part# 9100-2190 for an HP 6268A power supply. It has about 10 secondary connections mostly for control of the supply, it is NOT the main transformer. I can't find it anywhere or any source for it, any help appreciated.

If you want an HP part then HP spare parts at HP are the people to talk to - however I believe they still insist that you have an account with them and you must pay (if not a company) in advance.<p>I had to purchase a computer power supply from them on behalf of the company I once worked for - HP Australia did not keep spare packs for this particular model - they charged $129.00+P&P and it took 3 months for it to arrive from America.<p>colin

Don't panic its a nice power supply worth while.
Focus on one output at a time.<p>The primary must be dead so not as easy however the board gives you the information.<p>Draw out the transformer and concentrate on just one secondary at a time. Startworking your way back from a known point, drawing out the scheme as you go and the more details you fill in the puzzle starts to take shape but remember to concentrate on one entity at a time for example an LM7805 can be looked up for pinout and the LM7905 could be associated and linked back.<p>Honestly I am horrible at repair but if you can find a 5 volt IC or regulators that you can trace back and through process of elimination you will discover them one at a time. Sometimes schematics are just not there or are too expensive. HP has made some very nice products and hopefully your
PS will run again.

Hi you can try Tucker Electronics 18005274642. They used to sell parts for HP. Try Testequity
18005973457 too. Another hint is there could be a thermal fuse in the primary imbeded in transformer core. You will have to strip down the tape carefully on the primary side and look for the fuse [wider]wire connecting to the winding.
