Common questions
What does the Bus and Sensor Station Power Supply 1822440 do?
It supplies power to the Somfy Digital Network bus. Somfy lists it as the Bus and Sensor Station Power Supply, and it can also power Sensor Stations or Compact Sensors in an SDN or animeo IP system.
How many devices can it power?
Somfy rates it for up to 80 bus line devices, not counting motors. Motors on the network need their own power source, such as an SDN power panel.
What are its power ratings?
Somfy lists a 24V DC output and a 66 W consumption rating. It carries IC, FCC, CE and UL approvals and a 5 year Somfy warranty.
Does it work with animeo IP sensors?
Yes. Somfy lists power and data pass-through for animeo IP sensors, so one supply can feed the SDN bus and the sensor side of an animeo IP project.
Can it help during system setup?
Yes. Somfy notes it can act as a temporary configuration tool during setup when paired with a USB to RS485 adapter. This store carries the Somfy USB to RS485 Adaptor for SDN (9015260).
Which other SDN parts go with it?
Common partners include the SDN Data Hub V2 (1870951), the SDN Bus Booster (9027694) and the Power Panel 24V for Somfy Digital Network (1871026), which powers SDN motors.
