3.0 PROTECTION
When OVP ,OPP or short protection is triggered, the main outputs will be latched off. The main outputs can be
reset by cycling the DC remote on/off or AC power. +5Vsb output is auto recovery when fault condition removed.
3.1 OVER VOLTAGE PROTECTION
+3.3V output
3.84 Vmax.
+5.0V output

+12.0V output 14.2 Vmax.
3.2 SHORT Current PROTECTION
All output to GND.
3.3 OVER POWER PROTECTION
Foldback at 110%~150% over peak load
