DURATION SELECT SWITCH FOR AN EMERGENCY LIGHTING CONVERTER

An emergency converter device provides an interface for selecting an operation parameter for an emergency operation mode of the emergency converter device. The emergency converter device provides a supply current ILED to a load device, in particular to a lighting module including on or more light emitting diodes. The emergency converter device comprises a control circuit configured to set at least one operating parameter of the emergency converter device, an interface comprising a first terminal and a second terminal for connecting electrically a status indicator light emitting diode, and a detection circuit connected to the control circuit. The detection circuit is configured to detect a polarity of the status indicator light emitting diode connected to the first terminal and the second terminal, and the control circuit selects the at least one operating parameter of the emergency converter device based on the detected polarity.
