3. 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 4.5 Vmax.
+5.0V output 7.0 Vmax.
+12.0V output 15.6 Vmax.
3.2 SHORT PROTECTION
All output to GND.
3.3 OVER POWER PROTECTION
Foldback at 110%~150% over peak load
3.4 OVER CURRENT PROTECTION
+12V: 65A-80A
