3.8 3.3V Sense
A default 3.3V sense line should be implemented pin 13 of the connector.
3.9 Capacitive Load
The power supply should be able to power up and operate normally with the
following capacitances simultaneously present on the DC outputs.
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/+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.
4.2.2 Over Voltage Protection
The +12V/ DC output are protected against the over voltage condition .
Maximum value can't be over 15.5V at 12V.
4.2.3 Over Power Protection
The power supply can be used electronic circuit to limit the output current
against exceeding 10%-60% of surge output power or protected against
excessive power delivery since short circuit of any output or over total
power at high line.
4.2.4 Short Circuit Protection
Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will
auto-recovery.
