    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.
