About This

  • 【20kHz High-Frequency for Silent & Flicker-Free Light】 Experience ultimate quietness. Our 20kHz high-frequency PWM dimming technology pushes electrical noise beyond human hearing, eliminating buzzing sounds. By adopting this high-frequency PWM, it eradicates visible light flicker at its source. Enjoy perfectly stable and silent illumination from 1% to 100% brightness.
  • 【Advanced Flicker-Free Technology & Eye Protection】 This controller utilizes high-frequency PWM technology to eliminate visible light flicker, a key cause of eye strain and headaches. The stable, consistent light output mimics natural daylight, providing superior visual comfort for prolonged reading, work, or relaxation, effectively protecting your eyesight.

In the app, adjust brightness, fine-tune color temperature (2700K-6500K), and create smart scenes.
  • 【3 Control Methods】 This 2.4GHz WiFi CH21W LED controller supports simultaneous operation through: (1) RF Remote Control: Works with 2.4GHz remotes (RC01RFB, RC02RFB, RC07RFB, RC08RFB, WR02RF). (2) Smart App Control: Use Tuya Smart or Smart Life App via 2.4GHz Wi-Fi. (3) Voice Control: Compatible with Alexa & Google Home. All 3 control methods work together seamlessly.
  • 【Power & Installation】 Input Voltage: DC12V/DC24V. Output: 7.5A per channel. The controller operates in a wide temperature range (-25°C to 40°C). The required power supply must match your LED strip's voltage (e.g., DC12V for DC12V strips, DC24V for DC24V LED strips). Please note this package includes only the controller - LED strips and compatible power supply must be purchased separately for complete installation.
