4.2.5 Over-Current Protection
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.
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℃
5. Start Stability
5.1 No Load Start
When power is applied to DA1650-G 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.
