Hold up time:
14 ms typical @ 115 V
AC
This figure was obtained from the last AC line charging pulse to
the point where +5 V dropped down to +4.75 V.
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
thier 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.
General features
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 5.9 ~ 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.
Environmental specifications
Operating temperature:0 ~ 50° C, input 104/244 V
