Inverter Power Supply
A variable-frequency AC source that can stand in for the mains of any destination market — and for 400 Hz aircraft, marine and communications buses.
Built for the bench that has to look like every grid
The HPA series delivers maximum rated power for any output voltage up to 300 VAC (520 VAC per phase) and at any frequency between 40 Hz and 499.9 Hz. Input frequency is listed as 50 Hz, 60 Hz or 400 Hz.
Output is a galvanically isolated sine wave. PWM keeps the cabinet compact; an IGBT module is specified for efficiency, low noise and reliability. A 300% overload capability is published, with electronic / instant-trip / alarm protection for overload, over-temperature, instant cut-off and short circuit.

Questions buyers actually ask
Can one cabinet cover 50 Hz export goods and 400 Hz avionics?
The published output range is 40–499.9 Hz and the copy lists commercial 50/60 Hz plus communication, military, avionics and marine 400 Hz. Confirm the current rating for the 400 Hz point before treating it as dual-use.
Is the output isolated?
Yes. The page states galvanically isolated, with a no-harmonic-distortion (EMI, EMC) claim attached to that sentence.
