SilverStone SST-ST75EF [6/12] Protection

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.

Output Capacitive load (uF)

+5V

+12V

+3.3V

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.
