The power supply can be used electronic circuit to limit the output current
against exceeding 60% of surge output power or protected against excessive
power delivery since short circuit of any output or over total power at high line.

4. PROTECTION
The power supply should be able to power up and operate normally with the
following capacitances simultaneously present on the DC outputs.
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.
The +5V/+12V/+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 8.5~9.5V at 12V, 2.0~2.4V
at 3.3V.
4.2 Output Protection
4.2.1 Under 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.
4.2.2 Over Voltage Protection
Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.

5.1 No Load Start
When power is applied to ST70F-ES & ST60F-ES with no load connected or
under minimum load connected, neither damage to power supply nor hazards
to users will occur.

6.2 Altitude
6.1.1 Operating
The power supply shall operate properly when first applied at normal input
voltage and or so maximum load after 4 hours storage in 0 C environment.
4.2.6 Over-Temperature Protection
This power supply includes an over-temperature protection sensor, which can trip
and shut down the power supply at 110 C
The power supply can operate normally at any altitude between 0 to 10000 feet.

Current protection should be designed to limit the current to operate within safe
operating conditions. Over current protection schemes where only the voltage
output that experiences the over current event is shut off may be adequate to
maintain safe operation of the power supply and the system; however, damage
to the motherboard or other system components may occur. The recommended
over current protection scheme is for the power supply to latch into the shutdown
state. The setting of over current protection for each output rail is as following.
