In Mexico they frequently boost the voltage to deliver more power over old wires. My marina now puts out 129 volts and my Isolation transformer shut off while I was away in the US killing my batteries.
Is there a way to tweak the voltage switch to change at a higher voltage, say 131 volts? Can I input 240 and have it step down to 120 by the transformer. Or do I need to get the Transformer that does not have an auto switch. Any help would be appreciated.
