Arrangement for electrical power supply of load via transmission path divided into two has supply signal generator, first and second sub-paths for transmitting supply signal to and from load

摘要

The arrangement has a supply signal (S1) generator (30) and a divided transmission path with a first sub-path (41) for transmitting the supply signal from the generator to the load (20) and a second (42) for transmitting the supply signal from the load to the generator. The sub-paths are connected to the generator and load to form a closed circuit and both have voltage isolation arrangements. Up to 100 mW is transmitted to the load
