3-phase converter
3-phase converter
(OP)
We have some equipment placed on a lifting table powered by a 3-phase 400V motor.
This is the only device in the entire system requiring 3 phases.
The rest can easily run from a single 230V phase. A good one, that is (4-5 kW
The whole thing is mounted in a 20' container, making it mobile, but we may encounter locations without 3-phase power in the future.
I know you can get converters delivering 3-phase AC with only one phase in. High-power versions are used in windmills and trains, I guess, but how about something in the order of 5-7 kW ? (motor alone)
Or would it be a better solution to bring a fuel powered generator along should the problem arise ?

You can get a copy of his patents and figure out what he is doing. It is very simple and very elegant. Very worth considering.
Let us know what you decide on.
