Hi;
I searched the forum and could not find an answer to this, so here it goes.......
A little while back, I fabricated a little load-bank for testing my linear power supplies after rebuild. It is basically a 1 ohm resistor that I connect to the p/s to see how it performs. I have used this on A/R's and Midways and it has always worked perfectly, until now.
I am trying to test an Atari switching p/s using this rig but each and every time it goes into overload and shuts down. I tried using just a light bulb and it still shouts down.
It must have something to do with the p/s being a switcher vs. A linear but my lack of an EE degree prevents me from understanding why.
Is there any way to safely load a switcher out of the cab, (not hooked up to a board)?
Thanks in advance.
Jeff
