Power supplies
The Option 11C Mini AC power supply provides +5.1, +8, +15, -15, and -
48V. -120V/-150V is selected or disabled by DIP switch settings.
There is a 1.0 second start-up delay on the +5V rail.
An OVP (Over-Voltage Protection) circuit will shut down all outputs if the
+5 V output voltage exceeds the over-voltage threshold.
An under-voltage protection circuit will shut down all outputs if +5V output
is below the under-voltage threshold.
There is a 1.0 minute recovery delay from an under-voltage condition.
