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 damage 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.
