I would convert an ATX power supply from a computer. They are easy to find and can have very high amperage on the 12V rails. Look for one 500W or higher and can supply 30A at 12V. Then look to the right for the instructions for converting them for lab bench use.

No, you need a transformer. What's wrong with making one from a uwave oven transformer ?
