Common questions
What does this Somfy 12V DC plug-in power supply (1822445) do?
It powers a Somfy 12V DC WireFree motor from a standard wall outlet. Somfy offers it as a maintenance-free alternative to the reloadable battery tube, so the shade keeps running with no batteries to swap.
How long is the cable?
Somfy lists the cable at 9.9 ft (3 m). That length lets you run power from an outlet near the window up to the headrail, where the motor connects.
Which motors can it power?
It is made for Somfy 12V DC WireFree motors that run on an external battery, such as the Roll Up 28 WireFree RTS V2 External Battery motor (1241162). Check the WireFree Power Supply Compatibility Matrix on this page to confirm your motor.
Why choose plug-in power over batteries?
A plug-in supply gives the motor constant 12V DC power. You never recharge or reload a battery tube, which suits shades that sit within reach of an outlet.
Is there an alternate Somfy 12V supply?
Yes. The Somfy 12V DC Plug-in Power Supply with 9.9 ft Cable (1871529) is a matching option. This supply also powers the Somfy RTS 12V Dimming LED Control (1870607) for 12V LED lighting.
