FAQ

Q1: How should capacity be selected for continuous operation?

For long-term continuous duty, size the load at 70-80% of rated kVA.
This margin improves thermal stability and extends component life.

Q2: What happens to capacity at higher output frequencies?

≤120Hz: Full rated capacity available
>120Hz: Output power derates proportionally
400Hz: Typically limited to ~50% of rated kVA

This is due to magnetic and thermal constraints at high frequency.

Q3: What load types are supported electrically?

Resistive (heaters, lamps)
Capacitive (power supplies)
Inductive (transformers, motors)
Non-linear electronic loads

Total kVA and inrush must remain within limits.

Brought an Old German Machine Back to Life – This Thing's a Beast

Had a piece of industrial equipment shipped over from Europe that needed 400V 50Hz three-phase power. My shop runs on 220V 60Hz, so I figured I was out of luck. Stumbled across this converter and figured it was worth a shot. Hooked it up, dialed in the voltage and frequency, and the machine fired right up – smooth as butter. The digital readouts on the front are super handy – lets me see exactly what's going on without having to guess. Runs my equipment all day without breaking a sweat. It's heavy – took two of us to get it in place – but that's what you want for something that's gonna run day in and day out. If you're dealing with imported gear or just need to match weird power requirements, this thing's a lifesaver. Pricey? Yeah. But way cheaper than replacing a whole machine or rewiring your whole shop. Solid investment.
