Think of it in terms of hysteresis loss and eddy current, which are proportional to freq. Eddy current loss would depend on construction (hi-R magnetics and lam thickness). Might want to verify xfmr temp. And it may be noisy.
The biggie is to never use a 400Hz xfmr at 60Hz (core sat). If you are feeling froggy, fun to run 100kVA, 60Hz distribution xfmrs at 1000Hz - try it at least once.

Can we use an isolation transformer rated at 60Hz, 150 VA? The EUT draws about 10W. Your input is most appreciated.
