Beschreibung
Zusammenfassung:	A fan system includes: two circuit breakers, a control module for controlling two circuit breakers, two electric motors to which their operating voltage UB is supplied via the circuit breakers, and at least one temperature sensor on a board on which the circuit breakers are located. The control module evaluates a signal TNTC from the temperature sensor, and sets the pulse duty factors TV1, TV2 of pulsed control voltages at the circuit breakers, while taking into account this signal as well as a requested fan power, in such a way that no power loss PV exceeding a specified value occurs at any circuit breaker.
