Since ASi transmits power and data simultaneously via the yellow cable, the DC power supply must be decoupled from the AC communication. In the past, this was implemented in a special ASi power supply. Bihl+Wiedemann has integrated this data decoupling in all current gateways, so that all devices can now be operated with ordinary 24 V power supplies. However, there are limitations related to maximum cable length and performance. To ensure efficient supply to the participants, as well as use of the full cable length, we recommend our new range of power supplies. This is also optimized for ASi-3 and ASi-5 communication.
