Isolation Tranformer at 100V in Japan

Hello, I was about to purchase Isolation Transformer 3600W Auto for my sailboat and then realized that it only supports 115 or 230V. I am planning to utilize my boat primarily in East Asia, between Korea and Japan.


The thing is that Japanese use 100V. If I were to use an isolation transformer on while my boat is connected with 100V Japanese shore power, will it be a big problem? I know that it is not recommended but trying to see if the risk is worth doing it or not.

@Chang Woo Lee It will be fine as you can see from the specification it will accept a supply of 88-130V.

"3600 Watt Auto 115/230 V

This model will automatically switch to 115 V or 230 V supply, depending on input voltage. Supply 88 V – 130 V: switches to 115 V supply

Supply 185 – 250 V: switches to 230 V supply range.

Note: The AC input voltage is raised by 1:1.05 ratio at the AC output."
