RTCA DO-160G §16
DO-160 Section 16 Power Input Testing
Revision G
AC source 0–180 V L-N across 360–800 Hz with per-phase amplitude control, amplitude and frequency modulation engines, sub-millisecond slewing and controlled interrupt ramps. DC source to 80 V or 425 V depending on bus, with audio-frequency ripple injection.
This standard turns on
- category-based test matrix
- momentary interruptions
- voltage and frequency modulation
And says nothing about
- semiconductor reliability
- automotive voltage classes
