I was given a nice 120v switching power supply that I now use for all my 120vdc stuff.

Before that I hooked a bridge rectifier and electrolytic up to a small variac and plugged it into the wall - be careful with that!

The 120v coil in mine measure 86 ohms, so 1.4 amps

There are several different coil voltages - see page 7

Hi all:

Some time ago there was a discussion on a heavy duty DC power supply for the Wheatstone Perf. (WPE3/ISS)

And I believe someone made one for it.

I would like to build one and am looking for part #s and specs.

I am sure it would take more than 300mA! :-)

Any help appreciated.

Thanks in advance!
