## Summary description

Rotary dimmer Kontakt‑Simon DS9L.01/11 for dimmable LED lamps, rated for 230V and a load range of 2–250W. Designed for in‑wall installation to adjust light level smoothly via a rotating knob. Suitable for residential and commercial interiors where compatible dimmable LEDs or low‑power loads require manual brightness control.

## Long description

Rotary dimmer Kontakt‑Simon DS9L.01/11 is a wall-mounted control for dimmable LED lamps and other compatible low-power lighting loads. Rated for 230V AC and a usable load range of 2–250W, this dimmer provides manual, stepless adjustment of luminous intensity via a rotary knob and is designed for installation in standard flush-mounted electrical boxes in residential and light-commercial interiors.
Advantages
The DS9L.01/11 offers smooth, stepless dimming over a wide load range, making it suitable for modern dimmable LED sources while maintaining compatibility with small incandescent or halogen loads within the specified range. Its rotary control gives precise tactile feedback for incremental brightness changes, and the compact in-wall form factor allows installation behind standard faceplates without altering room aesthetics. The white finish integrates with common interior designs and simplifies replacement of conventional switches.
Suitable for
 Adjusting brightness of dimmable LED lamps in living rooms, bedrooms and kitchens
 Manual light control in small offices and reception areas
 Retrofit projects where existing in-wall switches are replaced with dimming controls
 Zones with low-power lighting loads requiring stepless adjustment
Key specifications
 Supply voltage: 230V AC
 Rated load range: 2–250 W
 Control type: rotary (stepless)
 Mounting: in-wall / flush-mounted in standard electrical box
 Finish: white
 Suitable loads: dimmable LED lamps and compatible resistive/low-power lighting
How to use
Install the dimmer into a compatible flush-mounted box following local electrical codes and switching off the circuit at the breaker before wiring. Connect the incoming live and switched live conductors to the dimmer terminals and secure the unit to the mounting frame; neutral is typically not required for simple phase-cut dimmers—consult the technical manual during installation. Rotate the knob clockwise to increase brightness and counterclockwise to decrease; some installations may include a push function to switch the light on or off.
Usage recommendations
Verify lamp compatibility before use: test with the intended dimmable LED lamps to confirm smooth operation across the specified 2–250 W range. For stable performance, use lamps and drivers that explicitly state compatibility with leading-edge/phase-cut dimmers. Avoid operating below the minimum load to prevent flicker, and consult a qualified electrician for multi-way or specialized control circuits.
