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 overcurrent condition persists beyond a few
milliseconds, the module will shut down into hiccup mode and restart once every 344mS. The module operates
normally when the output current goes into specified range. The typical average output current is 0.3A during
hiccup.
