I don't think they make any FerrUPS anymore. Those were based on a
massive ferroresonant transformer which, yes, is very sensitive to the
input frequency. Specifically, they don't like generator power, unless
it has extremely well regulated frequency output (such as a DC generator
with a digital sinusoidal converter)
