3. PROTECTION
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V1,+12V2,
+12V3 +12V4 +12V5,+12V6 outputs from exceeding the values shown in the following
Table.If the current limits are exceeded the power supply shall shutdown and latch off.
3-1. Over current protection
Voltage
+5V
3-2. Under voltage protection.
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown
state when +12V,+5V & +3.3V outputs under 85% of it's maximum value.
3-3. Over voltage protection

The over voltage sense circuitry and reference shall reside in packages that are separate
and distinct from the regulator control circuity and reference.No single point fault shall be
able to cause a sustained over voltage condition on any or all outputs. The supply shall
provide latch-mode over voltage protection as defined in Table.
