Energy and data transmission system for providing data coupled electrical power supply to e.g. sensor, has regulating devices regulating output voltages of lines so that current changes within bus subscriber are compensated
The system (5) has a transmission medium (80) including two lines (83, 85). A subscriber (30) has an integrated circuit (50) including a transmitting and receiving device for transmitting and receiving data according to a predetermined communications protocol and a decoupling device for providing a supply direct voltage. The decoupling device is an integral part of the circuit. The lines are provided with respective regulating devices. The regulating devices regulate output voltages of the lines so that the current changes within the bus subscriber are compensated.
