<p>The circuit has a galvanically isolated transmitter e.g. optocoupler (101), photovoltaic driver and transformer, for receiving applied control signals (E1, E2). A power section (130) is activated by the galvanically isolated transmitter as a function of the control signals. The control signals are generated by a bus system i.e. digital addressable lighting interface (DALI)-bus system. The galvanically isolated transformer and the power section are connected to a supply unit (110), where the supply unit comprises an electrical switch (Q3) that switches off the power section in a standby mode. An independent claim is also included for a method for operating a circuit for controlling an operating device.</p> |
