AWS-8248V User’s Manual 30

Overshoot (resistive load):

Any output overshoot when the power is turned on does not exceed 10%

of the nominal output voltage.

Output power: Maximum continuous: 310 W

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
