7.  Output Protection

 7.1         Over Voltage Protection

 The +5V/+12V/+3.3V DC output are protected against the over voltage condition. Maximum value can't be over 6.5V at 5V terminal and 15.5V at

12V, 4.3V at 3.3V.

 7.2         Over Power Protection

 The power supply will be shutdown and latch off when output power is

110%~150%.

 7.3         Under voltage protection

 In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state when +12V,+5V & +3.3V outputs under 60% of it's maximum value.

 7.4         Short Circuit Protection

 Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.

 7.5          Over-Current Protection

Current protection should be designed to limit the current to operate within safe operating conditions.
