Over Temperature Protection
The OTP is achieved by thermistor R25 and the threshold is set at 120C in non-latch mode; the hottest
component Q13 reaches 125C with 100LFM air flow correspondingly. It will restart automatically when the
temperature falls down to 110C. The protecting point will be varied a little under different conditions (air flow,
ambient temperature, input voltage, load...).
The hottest component on the top side: Q13
The thermistor on the bottom side: R25
