4. Protection

4.1 Input Protection
In primary circuit of the power supply , a protected fuse is inserted. Only internal
fault of the power supply will cause the fuse blown. Any overload or short circuit
at DC output will keep from fuse brown or fire hazard.

4.2 Output Protection

4.2.1 Under voltage protection
The +5V/+3.3V DC output are protected against the under voltage condition.
Range value can't be exceed 3.3~3.7V at 5V terminal and 2.0~2.4V at 3.3V.

4.2.2 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.

4.2.3 Over Power Protection
The power supply can be used electronic circuit to limit the output current against
exceeding 50% of surge output power or protected against excessive power
delivery since short circuit of any output or over total power at high line.

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