General features
Efficiency:
65% typical when measured at nominal input and rated load.
Input protection:
Protection against wrong polarity if the +24 V input voltage is mistakenly
reversed.
Output protection:
If for some reason the power supply fails to control itself, the built-in
over-voltage protection circuit will shut down the outputs to prevent dam-
age to external circuits. The trip point of the
crowbar circuit is approximately 5.7 ~ 7.0 V. The power supply will go
into hiccup mode under short circuit or overload
conditions, and will recover automatically when such conditions cease to
exist.
