Abstract
The invention relates to a device for supplying power to measuring sensors and transmitting a synchronous clock signal thereto, in particular, for a low-voltage switchgear, with a power supply unit () whose output signals are transmitted to the measuring sensors via transformers providing the isolation. A quartz-controlled oscillation circuit arrangement (quartz-controlled clock generator) is provided whose output signals are supplied to the power supply unit () so that the clock frequency of the power supply unit output signals is the same for the primary sides of the transformers (), the frequency lying within the operating range of the transformers ().
