Line regulation:
The output line regulation for each output is less than ±1%, when mea-
sured at each output's respective rated load and under ±10% changing
input voltage conditions.
Load regulation:
The values for each of the following output numbers were obtained by
changing each output load ±40% from the 60% rated load, whilst simulta-
neously keeping all other outputs at 60% of their respective rated loads.
Power good signal:
When the power is turned on, the power good signal will activate 100 to
500 ms after all output DC voltages are operating within their respective
regulation limits.
Power fail signal:
This will activate at least 0.5 ms before any of the output voltages fall
below their respective regulation limits.
B.3.1 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 approxi-
mately 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.
