I've run into cute tricks like a big Lambda 12V power supply, that had
a 10 ohm resistor in series with the AC power lead. When the power
supply output finally stabilized, a relay would short out the 10 ohm
resistor so that full power could be delivered. That works great
until the relay contacts arced closed, causing the PS to suck full
current on startup and blowing the fuse. It took a while to find that
one.

It's a Lambda LFS-48-24. Schematic is on Pg 6.

all the lambda stuff I've come across is bizarre in design and
construction.

I don't recall the model, but one was just a plain switching supply of a
few hundred watts with a gigantic wirewound power resistor in it. Nobody
else does that, nor do most places change their name every 5 weeks either-
lambda, nemic, veeco, tdk, wtf?
