PWM RGBW 4CH – LED Controllers with Dedicated White Channel

RGBW: multichannel color and real white for versatile lighting

Standard

The PWM RGBW 4-channel controllers are designed to manage RGB + White LED strips and modules. They operate at constant voltage 12/24/36/48 V DC (depending on the model) and provide independent control of the red, green, blue, and white channels. These are point-to-point systems that do not require gateways or complex home automation platforms.

System architecture

  • Flush-mounted controllers (502/503/standard boxes) with push buttons, potentiometer, or touch panel.
  • 4CH constant voltage PWM outputs for connecting RGBW LED strips, modules, or multicolor projectors with dedicated white.
  • Optional auxiliary control: some models support RF remote control for remote management.
  • Point-to-point topology: each controller manages its own load, without multi-point synchronization.

Advanced Features

  • Dedicated white channel: real, dimmable white (not just RGB mix).
  • More white power: suitable for functional and decorative/accent lighting.
  • Simulated dynamic white: W+R for warm tones, W+B for cool tones.
  • Wide color range: independent 4-channel control for customized scenes.
  • Deep dimming <1%: smooth, flicker-free transitions.
  • High PWM frequency: 250–500 Hz (entry), 1–4 kHz (mid), 8–16 kHz (high-end), stable dimming, photo/video ready.
  • Comfort & flexibility: ideal for spaces requiring both functional light and ambiance.
  • Wall panel: single control to quickly switch from work white to chromatic scene.

Typical Applications

  • Circadian cycles + chromotherapy: studios, mini-clinics, SPAs and wellness centers.
  • Emotional shower: light/color sequences with sounds and scents.
  • Residential: living rooms, kitchens, home theaters and bedrooms with real white + effects.
  • Hospitality: hotel rooms and scenic environments.
  • Retail: showcases and exhibition areas with functional and accent lighting.
  • Events/installations: dynamic solutions for exhibitions, fairs and decorative spaces.
  • Small independent spaces: relaxation rooms and wellness areas.

Available types

  • RGBW 4CH: independent control of red, green, blue, and white channels for dynamic scenarios and real white light.
