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 5A during
hiccup.
Test condition: Vin=48V

Over Temperature Protection
The OTP is achieved by thermistor R25 over the threshold is set at 125C in non-latch mode; the hottest
component Q13 reaches 130C with 100LFM air flow correspondingly (In fact, the hottest component H1 reaches
100C with 100LFM air flow correspondingly). It will restart automatically when the temperature falls down to 100C.
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
