Abstract: A method and a device for supplying energy to a low-voltage load using an electronic power supply device. The method involves: a) setting the power supply device to be able to provide an output current to the low-voltage load up to a specified peak current value upon demand; b) monitoring the output current (IL) provided to the low-voltage load by the electronic power supply device to detect an increase of IL over a threshold (IN) which is lower than the peak current value, c) if an increase of IL to an increased output current value higher than IN is detected, detecting the increased IL value and ascertaining an output current pulse duration (tPulse) based on the increased current value; d) providing IL at the level of the increased current value for the duration of the ascertained tPulse; and e) providing the IL at the level of IN after tPulse has expired.
