Abstract
An emergency converter device for lighting applications provides a supply current to a load device such as a lighting module. The emergency converter device has a printed circuit board arranged within a housing. A control circuit such as a microcontroller and a non-volatile memory for storing log data are arranged on the printed circuit board. An interface is configured to connect mechanically and electrically at least one of a status indicator light a test switch or a duration link select switch. The interface has a first connecting element and a second connecting element. The emergency converter device has a connecting means for connecting a data output terminal (USART_TX) and a data input terminal (USART_RX) of the control circuit to the exterior of the housing.
