Power good and power fail signals (optional):
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.
The power fail signal will activate at least 1 ms before the +5 V output
voltage falls below its regulation limit.
Short circuit protection:
A short circuit placed on any output to ground is shut down. When the
short circuit conditions have ceased to exist, power will then be recycled
to restart the power supply.
Over-current protection:
The power supply will shut down all the DC outputs when any output is
overloaded beyond its current limit or beyond its nominal line voltage
limit. When the over-current conditions have ceased to exist, power will
then be recycled to restart the power supply.
Current limit ranges: 5 V: 32 ~ 45 A
12 V: 13 ~ 20 A
-12 V: 6 ~ 12 A
-5 V: 1.5 ~ 3 A
Over-voltage protection:
The power supply will shut down all the DC outputs when any output
maximum voltage limit is exceeded. When the over-voltage conditions
have ceased to exist, power will then be recycled to restart the power sup-
ply.
Voltage limit ranges: 5 V: 6.25 ±0.75 V
12 V: 14 ±1 V
-5 V: -6.25 ±0.75 V
-12 V: -14 ±1 V
