The Bus Power Supply for Somfy Digital Network (SDN) provides 24V DC power for up to 100 controls and distribution devices on the SDN bus. A separate Bus Power Supply can be used for 1 Compact Sensor or 1 Sensor Station. The Bus Power Supply cannot be used to power motors. The Bus Power Supply is fault-tolerant, ensuring reliable operation should installation or wiring errors occur.
Also provided is a SDN data pass-through input for in-line connection anywhere on the bus without splitters or hubs. For bus segments with more than 100 devices, multiple Bus Power Supplies can be joined through the pass-through connection providing power
segmentation without additional wiring considerations.
