Need 220V 50Hz Power Supply
Need 220V 50Hz Power Supply
(OP)
I need to do some testing with a power supply that simulates the power utilized in Germany. I need it to be as close to perfect as possible. I'm looking for a converter that is affordable. I've seen inverters but I'd prefer something that ran off of US 120V 60Hz line power. I found one that does all sorts of ranges/frequencies however it's $5k-10k.
Does anyone have any sources for something like this? When I do a search all I can find are power supplies that WORK with 220/50 instead of ones that generate.
I've tried gasoline generators and their frequency is not stable enough to replicate true 50Hz.
Thanks!

RE: Need 220V 50Hz Power Supply
1) Buy a generator 50 Hz or 60Hz you can crank the frequency down on. I've done that for testing numerous times.
2) Acquire a few batteries and use a 50Hz inverter.
If it's a 3 ph load go the generator route, if it's a 1ph load do either.
If you like spending great gobs of money buy a test source.(generally absurd)

Yeah, they're expensive, but you can rent them...

9 degrees F is not considered "very nice".

I've had good luck with one of the marine brands of inverters for boats. I can't remember the brand at the moment so I'll post it tomorrow as it isn't one of the brands that pops up near the top of Google.

Depending on the type of load (inductive, capacitive) would also determine if a frequency converter could do it.

Try a small diesel generator instead of a gasoline generator. Small gasoline generators often use a flap in the cooling air path as the control element. The frequency wanders like a rag in the wind. Even the small diesel generators use a centrifugal governor and are much more frequency stable than a small gasoline generator. (But not as good as an inverter generator.)
