3.0 PROTECTION
When OPP, OVP,OTP 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.

Foldback at 115%~150% over peak load
3.2 OVER VOLTAGE PROTECTION
+3.3V output 5.2 Vmax.
+5.0V output 7.0 Vmax.
+12.0V output 16 Vmax.
3.3 SHORT PROTECTION
