According to Sola's PDF for its CVS series of constant-voltage
you can expect the output voltage to rise about 1.5% for each 1% rise in
the frequency. So, freq goes up 1Hz, 1/60 = 1.7% x 1.5 = 2.5% x 120V =
This is true for their CVS series transformers---with other models, YMMV.
Hmm, they say the efficiency is up to 92% full load, makes me wonder
what it is on average at more typical load. Sounds like those things
burn up a lot of extra juice.
