  Over current is a fault condition defined as a 1A/Sec current ramp starting from full load applied to the output                                             
under test. The other outputs may be set to any condition defined in the PSU parametric 
specification. A fault on any output will cause the rest of the outputs to latch off/Recovery (also see exception notes 
below).  
Notes:
1. The output current limits will be satisfied throughout the entire operating temperature range as defined 
     in Section 5.4
2. A fault on any output other than Standby will not cause the Standby to turn off. A fault on Standby will 
    cause the other outputs to turn off but not latch off. 
3. The Standby output will not latch off. It must return to normal operation once the fault is removed.
4. Under any continuous loading conditions allowed by the over current protections, the power supply 
     shall not be damaged.
