Product information

Description

Synergy21 S21-LED-SR000079 is an external rotary dimmer designed for DC 3 V control, housed in a compact black enclosure measuring 86×86×32 mm. The device provides manual, stepless brightness adjustment via a tactile rotary knob and is intended for single-circuit low-voltage LED installations where an external surface- or panel-mounted control is required. The mechanical knob and straightforward mounting dimensions allow integration into typical wall-box or panel cutouts for retrofit or new installations.

Advantages

The rotary design delivers smooth, continuous dimming without noticeable steps, offering precise manual control of LED light level. Electronics are tuned for LED loads to reduce flicker and extend usable dimming range compared with basic resistive controls. Its compact footprint and standard mounting make installation simple, while the knob interface provides an immediate, intuitive way to set ambient lighting.

Suitable for

  • Residential rooms requiring adjustable ambient lighting such as living rooms, bedrooms and dining areas
  • Small commercial interiors including offices, meeting rooms and reception areas
  • Single-circuit LED lighting installations using low-voltage, dimmable fixtures
  • Retrofit projects replacing non-dimmable or incompatible dimmers with an LED-compatible rotary control

Key specifications

  • Control type: mechanical rotary knob providing stepless dimming
  • Supply/control voltage: DC 3 V control input
  • Circuit type: single-circuit (mono) dimming for one lighting circuit
  • Mounting: wall-mounted, suitable for standard recessed wall boxes and surface mounting
  • Dimensions: 86 × 86 × 32 mm (width × height × depth)
  • Color/finish: black housing
  • Load compatibility: designed for dimmable LED loads and low-voltage LED systems when used within device limits

How to use

Mount the dimmer in a suitable wall box or on a panel according to local electrical codes and the manufacturer wiring diagram. Connect the live and load conductors and any control lines required for DC 3 V operation, then restore power. Rotate the knob clockwise to increase brightness and counterclockwise to decrease it. The unit provides continuous adjustment within its operational load range; do not force the knob past its mechanical stops. Observe polarities and grounding practices appropriate to the installation.

Usage recommendations

Use with LED fixtures explicitly marked as dimmable and ensure the combined load of connected fittings falls within the dimmer’s supported range. Avoid connecting non-dimmable lamps or loads outside the device specification. For multi-fixture installations, verify compatibility of LED drivers and lamps to minimise flicker and ensure smooth dimming. If unsure about wiring or compatibility, consult a qualified electrician to confirm proper installation and optimal performance.
