Over-temperature Protection (OTP)
The power supply is protected against over temperature conditions caused by loss of fan
cooling or excessive ambient temperature. In an OTP condition the PSU will shut down. When
the power supply temperature drops to within specified limits, the power supply will restore
power automatically, while the 12VSB remains always on. The OTP circuit has built-in margin
so that the power supply will not oscillate on and off due to temperature recovering condition.
The OTP trip level has a minimum of 4°C of ambient temperature margin.
