3.2 Over Temperature Protection
The power supply will be protected against over temperature conditions caused by loss
of fan cooling or excessive ambient temperature.In an OTP condition the PSU will
shutdown.When the power supply temperature drops to within specifide limits,the power
supply shall restore power automatically.The OTP circuit must have built in hysteresis
such that the power supply will not oscillate on and off due to temperature recovering
condition.
3.3 Over-power protection
The power supply will be shutdown and latch off when output power within 110~180%
of rated DC output.
Note: Assurance machine can work at low voltage,full load won't damage machine.
3.4 Under voltage protection
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown
state when +12V,+5V & +3.3V outputs under 85% of it's maximum value.
3.5 Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that are separate
and distinct from the regulator control circuity and reference.No single point fault shall
be able to cause a sustained over voltage condition on any or all outputs.The supply
shall provide latch-mode over voltage protection as defined in Table.
