Abstract

In order to achieve a universal, flexible and highly integrated operating device for driving various lamps, ensuring the protection of the entire operating device and of the appliances connected thereto by means of staggered protective measures at both the input and the output, starting from the preamble of claim 1, a first branch for connecting a lamp to a first of the interface circuits (SS1) and a second branch for connecting at least one communication module to a second of the interface circuits (SS2) are connected to the coarse protection circuit (G) which short-circuits an overvoltage of the mains voltage occurring at the input of the operating device. In the first branch, a line filter (NF) is connected to the coarse protection circuit (G) and a clamp circuit (K) consisting of the fine protection circuit (F) and of a first energy absorber (E1) is connected to the line filter (NF). When the residual pulse voltage is too high, the fine protection circuit (F) activates the first energy absorber (E1), the overvoltage pulse is short-circuited and the short-circuit is deactivated again when the mains voltage reaches the next zero crossing. A second energy absorber (E2) which, when…
