Compact RF LED Controller

The Ruth's sister ys-rfm1 is a wireless RF mini controller that manages monochrome, colour-temperature, RGB or RGBW LED strips from a single handheld remote. It accepts a DC 5 V to 24 V supply through a 5.5 × 2.1 mm female jack and drives the connected light bar directly without soldering. The unit measures 55 × 22 × 13 mm and weighs 30 g to 32 g depending on the 14, 17 or 21 key remote variant. Operating temperature spans -20 to 60 °C.

Replaces Wired Inline Dimmers

Builders who currently use a manual inline dimmer or a basic IR receiver can switch to this RF module for through-wall control and a wider choice of dynamic modes such as gradient, jump, fade, flicker and burst. The upgrade is worthwhile when the installation hides the strip behind a TV backdrop, under a bar counter or inside a bedside unit where line-of-sight remotes fail. It does not suit projects that require addressable pixel control or DMX integration.

Fits Tight Cove Spaces

The controller's 13 mm height lets it sit inside shallow coving, behind cornices or inside aluminium channels without increasing the overall profile. A single 5.5 × 2.1 mm DC input feeds both the controller and the strip, so only one power brick is needed for the whole run. The common-anode output matches standard 5 V to 24 V constant-voltage strips, leaving the installer free to choose strip length and density within the controller's unnamed current limit.

Questions about this item

What size DC power jack does the ys-rfm1 controller accept?

The unit uses a 5.5 × 2.1 mm DC female connector for power input.

How do I pair the 14-key RF remote with the controller?

Apply 5-24 V DC power, then press any remote key within three seconds to complete pairing.

Will the plastic housing become brittle after years at 60 °C?

The controller is rated for continuous operation up to 60 °C, so the enclosure materials are chosen to withstand that temperature.
