Technical FAQ

Frequently Asked Questions

What safety features are standard on Powerstax High Voltage Power Supplies?

All units include hardware safety interlocks, over-voltage/over-current limiting, short-circuit protection, fast arc detection, and thermal shut-down safeguards to protect both operating personnel and sensitive load equipment.

Can multiple HV power units be operated in parallel for higher power output?

Yes. Our modular topologies support active current-sharing parallel operation, allowing scalable power systems exceeding 500kW while retaining precise control and master-slave telemetry.

What is the typical lead time for standard vs customized high voltage units?

Standard catalog models feature fast manufacturing turnaround, while customized OEM platforms are prototyped and qualified rapidly thanks to our modular building block architecture.
