My boat is setup with 2 x 30 amp 110/120v shore power
, 7kw generator
110/120v and 3kw xantrex inverter/charger.
I want the option of 220/240v shore power
just to power the air con units. I've purchased a 4kva step-down transformer but this will give me 110/120v at 50Hz not the 60 Hz normally used at 110/120v.
Now, I've emailed the air con manufacturer and determined that the units will run but at reduced efficiency and that I must also only use the fans on high speed or they'll burn out.
So, finally, my question is... Is there a device that'll take a 50Hz supply and transform it to 60Hz? If so... What is it and what sort of cost?
Thanks in anticipation.
