Where can I get a transformer to convert 120VAC to 12VDC. A minimum of 10A of DC current is required. I don't need any type of housing or cords/wires. Open/exposed terminals on a transformer I can place inside a box is fine.
Thanks Dnkldorf. That is what I am looking for but the cost is much higher than I expected. Isn't it normally more "expensive" to convert from 12VDC to 120VAC than vise-versa? I'm sure the unit you showed me is of much higher quality than the "cheapy" 12VDC inverters at the big chain stores. However, for the same price, I can get one of those to convert DC to AC (same VA). Are there also "cheapy" versions of AC to DC converters? This is not for a job so top quality is not a necessity.

If you want to do your own rectifier, filter, & regulator, here is the 24VCT, 10A TX that they sell for $17.99 http://www.mpja.com/category/Transformers/24V_CT_(12-0-12)10A_TRANSFORMER_7846_TR.asp [This message has been edited by JoeTestingEngr (edited 12-12-2005).]

A PC power supply, like most switching supplies, will not work without a minimum load on the output. For a PC supply, that load would have to be on the 5V output, not the 12V in order for the supply to start up properly.
$85 seems completely reasonable for an industrial DIN rail power supply like that.

NJ, maybe some old PC supplies need a 5vdc load to start (particularly the old IBM PC/AT supply) but I have a buttload of them that don't. I have been using an assortment of PC supplies for bench supplies. They start fine without a load. Some will shut down when the load changed significantly, some don't
