Recently I have received a lot of inquiries from customers about magnetic track lights, the most frequently consulted by customers is the dimming method and wiring problems, now I will share with you the dimming method of magnetic track.
Common magnetic-track control approaches include 0-10V dimming, DALI-2, selected TRIAC (phase-cut) power arrangements, Casambi and Zigbee. Each requires compatible luminaires and control gear; they are not universally interchangeable. The 0-10V, TRIAC and DALI wiring images below are historical examples, not current model-approved installation drawings. Verify exact power supplies, decoders, luminaire drivers and terminals before wiring.
1. 0-10V dimming
In fact, for the 0-10V dimming, most of the wiring scheme on the market is the following diagram, 0-10V control requires compatible luminaire drivers and dedicated dimming signal conductors. The separate DC48V supply powers the track; the signal pair controls dimming. Confirm exact conductor assignments and polarity for the selected configuration
The trade-off for 0-10V control is its dedicated dimming signal wiring. If only mains live and neutral are available at the switch, assess the cable route and compatible driver architecture before choosing this option.
2. TRIAC Dimming
TRIAC phase-cut dimming works only with a confirmed combination of mains dimmer, suitable dimmable DC48V power supply and compatible luminaires. Never connect a mains phase-cut dimmer directly to DC48V track conductors. A validated mains-side solution may avoid separate control signal wires, subject to the actual equipment wiring diagram. The historical illustration below instead shows a separate TRIAC decoder with an independent 48V DC power supply; this is a different topology and must not be copied without validation against current hardware:
3. DALI-2 dimming
For the Topsund M20 48V magnetic track system, selected DALI-2 luminaire versions use a four-wire DC48V track: two power conductors and two DALI bus conductors. Compatible control gear supports individual addressing, groups and scenes. KNX integration requires a KNX-to-DALI gateway and a suitable DALI bus power arrangement.
The DALI/KNX image above is a historical concept illustration. It does not identify the gateway model, whether DALI bus power is integrated, or the verified terminal assignments. Do not use it as a construction wiring diagram. For a KNX-controlled M20 project, refer to the DALI-2 magnetic track lighting overview and choose compatible DALI-2 luminaires and a KNX-to-DALI gateway, then verify addressing, bus power and control wiring.
4. Bluetooth dimming
With the development of smart lighting, Bluetooth dimming is also applied more, and the solution is becoming more mature. Not only through the app on the phone, but also through the switch panel, infrared remote control for lighting grouping, scene mode setting . Direct Bluetooth luminaire control requires compatible modules or drivers. Casambi-to-DALI is a different architecture using a suitable bridge to control compatible DALI luminaires.
Topsund can offer selected Casambi control configurations, subject to driver, gateway and track compatibility review.
5. 2.4G dimming
Smart lighting can be controlled not only through a mobile app, but also through voice control. Some wireless control products use the 2.4 GHz radio band, but frequency alone does not define interoperability. Tuya app, voice assistant and gateway support must be confirmed against exact hardware and firmware.
6. Zigbee
Zigbee is a wireless mesh control protocol on selected Topsund luminaire configurations. Tuya, Philips Hue and other gateway compatibility must be verified by product and firmware; a Zigbee label alone does not guarantee interoperability.
Choose control based on wiring, individual addressing needs and verified hardware compatibility. M20 DALI-2 with a KNX-to-DALI gateway is suitable for compatible wired projects; selected Casambi or Zigbee configurations can serve wireless applications. Share the project specification for a compatibility check.
