Thermal Derating Curve
Maximum junction temperature of semiconductors derated to 120 degree C.
AIR FLOW Bottom view
Derating curve under 48V input The OTP is achieved by temperature sensor U10 and it is in non-latch mode when the hottest component Q12 reaches 120°C with 200LFM air flow correspondingly. It will restart automatically when the temperature falls down to 105°C. The protecting point will be varied a little under different conditions (air flow, ambient temperature, input voltage, load...).

Over Current Protection
To provide protection in a fault output overload condition, the module is equipped with internal current -limiting circuitry and can endure current limiting for a few mili-seconds. If the over current condition persists beyond a few milliseconds, the module will shut down into hiccup mode and restart once every 400mS. The module operates normally when the output current goes into specified range. The typical average output current is 4.8A during hiccup.
