110V 60Hz to 220V 50Hz Converter for 3kW Machines

Hi all,
I’m trying to run a few of our 220V/50Hz machines using a 110V/60Hz power supply (the standard in the US). Specifically, I need 4 or 5 step-up converters that can convert 110V to 220V and change the frequency from 60Hz to 50Hz.
Has anyone used such devices? Any product recommendations?

Yes, what you’re looking for is commonly referred to as a frequency converter, not just a transformer. We provide such converters, but to give the right recommendation, we’ll need a bit more information:
1. What kind of load are your machines? Motors, electronics, heaters, or a mix?
2. What’s the rated power (in watts) and current (in amps) of each machine?
Let us know and we’ll point you to the right product.

The machines are air-to-water generators, basically a combo of air conditioners and other electronics.
Max power: 3000W per unit
Rated Voltage: 220V
Rated Frequency: 50Hz
Max current: 5A (smaller model) to 12A (larger model)
We're looking to run about 4–5 of these.

Leif wrote:Thanks for the details! Since these are inductive loads (air conditioners), they draw a high surge current on startup. So, we’d recommend sizing up your converter.
For your needs, we suggest the 15kVA Single Phase Frequency Converter, which can convert 110V/60Hz to 220V/50Hz. This should be enough to handle the inrush current and run the machines safely.
