Running an US Fridge Compressor in Europe?
(1/7) > >>
ivaylo:
Hey guys,

A friend moved from the US to the Netherlands. Got her US wine fridge with her. The controls, displays, etc. all work, but compressor won't turn with any of the adapters she's tried (labels pictured). Must be the frequency difference (no idea if those adapters convert frequency, guess not), but I was expecting it if not run extended periods of time to at least turn?

Any product on the market which could help her?

Appreciate your help,
Ivaylo

I'd say those adapters don't work because the surge current of the motor is HUGE since it's essentially stalled on startup, likely forcing these into overload shutdown.

This fridge is so small, I'd invest in a real transformer. Something like these:

The usual fridge compressor motor relies on the line frequency.
Using a proper (and large enough) transformer, most probably it'll start to run, but will run slower than intended and may have increased power consumption. Both will result in decreased efficiency of the fridge. One might try some combination of charger, large enough battery and 60Hz / 120V inverter with large surge power capability, or just get a new fridge.

For a whine cooler made in China, it will cost you less to buy a new 240v50hz one than converting 50hz to 60hz with something like a true sine wave inverter connected to a DC power supply with enough startup surge current support for the compressor.

You also have to worry about the inverter setup being safe if you go the homemade solution.  Getting a proper 60hz sinewave out with that startup surge current support will cost money.
