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.
5. Start Stability
5.1 No Load Start
When power is applied to HPG-750BR-H14C with no load connected or under minimum
load connected, neither damage to power supply nor hazards to users will occur.
5.2 Cold Start
The power supply shall operate properly when first applied at normal input voltage and or
so maximum load after 4 hours storage in 0℃ environment.
