Re: Brand New FCB1010 240V model for sale


Transformers are designed for a specific frequency - not so much the windings as the material and design of the core.  But the difference between 50 and 60 Hz isn't much, and since it has the ability to switch, the core would have been designed for both.  Insulation matters more in the voltage rating than anything else in it's design.  Like just about everything else it costs more to design and manufacture a different part for every different spec, so if they can just design it once and cover a whole area of specifications, that's what they do.  Most mains transformers will handle 50 or 60 Hz, and 120/240 volts without an issue.  (But always check the specs, just in case!)
