Between each test, we wait for the LED on the DC-DC converter to turn on (indicating input < 45V), then off again, indicating input < 2.5V.

Note: The power supply has a current limit of 20A, and goes in to current limit on all the 140V tests. For the 80V tests, it did not noticeably go into current limit, but it might have internally given on the values measured.
Capacitor Discharge Time (from 140V - 30V):
