4. PROTECTION
The iLC CORE drivers are equipped with internal protection to ensure that the they and every component of the
luminaire in which they are installed operate correctly.
4.1. Short circuit protection
In the case of a short circuit in the load terminals, the driver goes into hiccup mode (power-on retries), in which it
remains as long as the fault continues. This protection resets automatically, so that when the short circuit event is
resolved, the driver comes out of protection mode and the power supply restarts.
4.2. Overload and open circuit protection
In the event of overload, the driver goes into protection mode, where it remains for a specific time depending on the
severity of the overload. The protection mode maintains a constant output, making it impossible to perform any type
of programming while it is in this mode. When the overload exceeds 150V, the driver goes into hiccup mode, where
it will remain as long as the fault continues.
In the event of an open circuit, the driver goes into hiccup mode, where it will remain as long as the fault continues.
If it is connected at a load lower than that permitted in the operating area, the driver will supply a current of 70mA as
long as this situation is maintained.
4.3. Thermal protection
The iLC CORE control gear benefits from thermal protection so that the power supplied is reduced when a temperature
excess is detected.
If, under normal operating conditions, the temperature at tc exceeds its maximum permitted value by 6ºC, the driver
will reduce the power supplied by up to 75% of the total.
If, during power reduction mode, the temperature at tc continues to rise until it exceeds its maximum permitted value
by 8ºC, the driver will reduce the load by up to 10% of the total.
While in either of the 2 power reduction modes, if the temperature at tc drops 6ºC lower than its maximum permitted
value, the driver will return to its initial normal operating mode.
This process is illustrated in the flowchart on the following page:
