2.4 Output Protection
Each DC output is protected from over voltage, over current and short circuit. The
following sections include the details for these protection mechanisms.
2.4.1 Over voltage Protection
The overvoltage sense circuitry and reference reside in packages that are
separate and distinct from the regulator control circuitry and reference. No
single point fault is able to cause a sustained overvoltage condition on any
or all outputs. The power supply provides latch-mode overvoltage
protection defined as:
+5V output is between 5.74V to 7V
+12V output is between 13.4V to 15.6V
+3.3V output is between 3.76V to 4.8V
2.4.2 Over Current Protection
The power supply should provide +5V, +3.3Vand +12V OCP and should
shutdown of each output power. For testing purposes, the overload currents of
each tested output rail should be ramped at a minimum rate of 10A/sec.
2.4.3 Short-circuit Protection
The short circuit placed on +3.3V, +5V, + 12V, –12V and 5Vs output shall
cause no damage and the power supply shall shut down or latch.
3 Mechanical
3.1 AC Connector
The AC input receptacle is an IEC 320 type or equivalent. In lieu of a dedicated
switch, the IEC 320 receptacle may be considered the mains disconnect.
