I used to have quite a few of an older type of those - giv= en to me surplus.=C2=A0 =C2=A0An RS232 drive signal will drive one quite ha= ppily - they are designed to be driven from logic signals.
The 25A rati= ng would be enough for your PSU, I think mine were rated at a bit more.

Hello Peter,

Neat, and thank you, but clicking on Andy's exe file is temptingly

would drive something like this directly, or would a big input surge
be likely to kill it?
