3.8 Protection
3.8.1 Over Power Protection
This power supply shut down all DC outputs when the outputs are
overloaded to the limit. The power supply logic shall latch into the off state,
the power supply shall return to the normal operation only after the fault has
been removed, and the PS-ON, or AC input, has been cycled OFF/ON with
a minimal OFF time of 1 second.
CONDITIONS
LIMITS
90/180VAC input When output power is over to 110%~130%
3.8.2 Over the Voltage Protection
The power supply shall latch off if the +5 VDC or +3.3VDC or +12 VDC
maximum voltage exceeds the limits shown. The power supply logic shall
latch into the off state, and the power supply shall return to normal operation
only after the fault has been removed, and the PS-ON, or AC input, have been
cycled OFF/ON with a minimum OFF time of 1 second.
+5 VDC
CONDITIONS
LIMITS
All operating
5.6 VDC 6.5 VDC
+3.3 VDC
CONDITIONS LIMITS
All operating 3.8 VDC 4.3 VDC
+12 VDC
CONDITIONS LIMITS
All operating 13.6 VDC 15.6 VDC
3.8.3 Short Circuit Protection
A short circuit that has been placed on any output shall cause no damage to this unit.
The short circuit is defined as any output impedance of less than 0.1 ohms.
3.8.4 No Load Operation
When primary power is applied with no load on any output voltage, no
damage or hazardous conditions shall occur. In such a case , the power
supply shall power up and stabilize.
