Many people believe that to create “smart” lighting, you must throw out your old chandeliers and replace all the lamps with expensive Smart-analogues. The TRIAC (Phase-cut) protocol proves the opposite. This is a technology that allows you to adjust the brightness of ordinary 230V dimmable LED lamps, sconces and chandeliers using only existing wiring. Thanks to Sunricher equipment, TRIAC has ceased to be just a “button on the wall” and has become part of professional DALI, Bluetooth and RF systems.

1. Controllers and dimmers: Control power 230V
These are devices that directly control the voltage going to the lamp. They allow you to smoothly change the brightness from deep evening dimming to bright work light.

  • RF control versatility: The SR-1009SAC-HP model is a powerful dimmer that can be controlled using radio remote controls. It is ideal for modernization when you do not want to cut through the walls for new switches.
  • Large-scale DIN-rail solutions: For large facilities where all the equipment is assembled in a switchboard, the SR-2303AC-4CH-DIN is used. This is a 4-channel monster that allows you to control four independent groups of lights (for example, living room, kitchen, corridor) from one module.
  • Smart integration: The SR-SB9101SAC-HP adds Bluetooth Mesh control to the classic TRIAC lamp. Now your favorite chandelier "sees" your smartphone and SR-BUS series remote controls.
2. Converters and gateways: Bridges between protocols
This is the most interesting part of the Sunricher line. A situation often arises: the control system is one (for example, DALI), and the lamps are completely different.
  • DALI to TRIAC: If you have a professional DALI system, but you have purchased a designer lamp that works only from 230V, the SR-2303SAC-HP or DT-AC converters will help you. They translate digital DALI commands into a language understandable to a conventional dimmer.
  • TRIAC to PWM (for LED strips): The unique V1-S device. It allows you to control a low-voltage LED strip (12-24V) using a conventional wall-mounted TRIAC dimmer. This is a real salvation for designers who want to maintain a single style of switches throughout the house.


























3. Professional drivers: All-in-one
For those who do not want to assemble a designer from separate blocks, there are combined solutions, such as SRPC-TRIAC-24-200CV.
This is a powerful 200W driver that understands almost all protocols at once:
  • DALI (digital control);
  • Push-Dim (control of a conventional doorbell button);
  • TRIAC (control of a phase dimmer);
  • 0/1-10V. It converts 230V into stable 24V for the tape, providing ideal light quality.

4. Why is TRIAC still relevant?
Advantages:
      1) Savings on wiring: You only need a standard cable (phase + zero). You do not need to pull an additional control bus to each luminaire.
      2) Huge selection of lamps: Most modern chandeliers and sconces with dimming function work precisely according to the TRIAC protocol.
      3) Budget: The implementation of TRIAC dimming is usually cheaper than a full DALI system.
      4) Reliability: The technology has been developed for decades, and modern Sunricher electronics have eliminated the main disadvantage - flickering at low brightness.
Disadvantages:
  • Requires high-quality dimmable LED lamps (not every LED lamp can dim).
  • Has restrictions on the minimum load (if the lamp is very low-power, it can flicker without a special bypass).

Conclusion
TRIAC from Sunricher is an ideal solution for those who value traditions, but want to keep up with the times. Thanks to gateways and converters, you can start with a simple dimmer, and later integrate it into a complex smart home system.
