[Milsurplus] More High Frequency Power

[J. Forster]

They may well run hot because of the increased eddy current losses in the iron.
800 Hz transformers have thinner laminations. than 60 Hz. Try hooking them up
with no load and see how hot they get. (If they are not potted) If  too hot to
touch after a half hour or so, look for another way.  If they are potted you
should measure the power into them with no load. If it's more than a few watts,
try something else.

Also, sometimes the input of 800 Hz gear can be strapped to run on 80 V, BTW. My
ASB-5 is like that. It's worth a look.

FWIW,

John
