Product information

Description

Synergy21 S21-LED-SR000044 is a built-in dimmer module for indoor LED lighting control. Housed in white and operated via a button control, the unit accepts 3 V DC and communicates wirelessly at 868.3 MHz with a typical indoor range up to 15 m. Weighing 100 g, the compact module is designed for integration into wall switch locations or junction boxes to provide on/off switching and smooth brightness adjustment for compatible LED fittings.

Advantages

The device provides flicker-free dimming and stable performance when used with explicitly dimmable LED drivers and lamps. Button control offers a straightforward user interface for everyday operation, while the small form factor enables installation in standard single-gang switch boxes or similar recessed mounting points. RF communication at 868.3 MHz supports remote integration or pairing with compatible systems where wireless control is required.

Suitable for

  • Residential rooms where LED lighting requires dimming and simple wall-mounted control
  • Small commercial spaces and offices needing local manual dimming and wireless control capability
  • Retrofit projects replacing standard switches with LED-compatible dimming modules
  • Junction box installations where a compact built-in dimmer is preferred

Key specifications

  • Control type: button control for on/off and dimming
  • Power input: 3 V DC
  • Wireless communication: 868.3 MHz RF with up to 15 m indoor range (typical)
  • Color / housing: white
  • Weight: 100 g
  • Mounting: built-in for wall switches or junction boxes, compact form factor

How to use

Turn off mains power before installation and follow local electrical codes. Mount the module in a compatible wall switch location or junction box, and make electrical connections according to the luminaire and dimmer wiring diagrams. After restoring power, use the button control to switch the connected LED lighting on and off and to adjust brightness. If integrating with a wireless system, follow the manufacturer’s pairing procedure to register the device on the RF network at 868.3 MHz.

Usage recommendations

Use only with LED luminaires and drivers explicitly specified as dimmable and compatible with the dimming method supported by this module. Verify that the driver or lamp manufacturer permits the applied control technique and confirm adequate load range to avoid unstable behaviour. For wireless integration, ensure line-of-sight or minimal obstruction within the stated indoor range for reliable communication; when in doubt, consult a qualified electrician or the luminaire manufacturer.
