split power supply

ocool_15 · 16th December 2004, 09:24 PM

If I need a split power supply is it possible to use 2 DC wall adapters wired in series? Would that damage the caps inside them? If i need something permanant I'll do something better I just need something to test it.

check the polarityof the outputs when tied together, they are truly in series especially if of different makes.they might be not the same

Be careful. Sometimes the negative is connected to earth. This means that one of the DC adapters would be shorted if you connect them in series.

Check with a meter first.
