DC 5-24V Touch PWM LED Dimmer Driver Module 5A – COB Strip
DC 5–24V Touch PWM LED Dimming Driver Module — Smooth Stepless Brightness Control
Take full control of your LED lighting with this compact, high-efficiency PWM (Pulse Width Modulation) Touch Dimming Driver Module. Designed for hobbyists, DIY builders, and lighting professionals alike, this module delivers smooth, flicker-free stepless brightness adjustment for LED strips, COB light strips, light bars, and panel lights — all via a responsive touch-sensitive button.
Key Features
- Wide Voltage Compatibility: Accepts DC 5V to 24V input, making it adaptable to a broad range of power supply setups.
- Smooth Stepless Dimming: PWM technology delivers seamless brightness transitions with zero visible flicker, thanks to a high switching frequency of 23 kHz (230,000 Hz).
- Constant Voltage Output: Built-in constant voltage circuit protects your LED strips and extends their operational lifespan.
- Intuitive Touch Control: Short press to toggle on/off; long press for continuous brightness adjustment — simple and responsive every time.
- Memory Function: Remembers the last brightness setting after power is cycled, so you're always right where you left off.
- Versatile Compatibility: Works with DC LEDs, COB light strips, light bars, and light panels that use resistance current-limiting designs.

How It Works
This driver module uses Pulse Width Modulation (PWM) to rapidly switch the LED output on and off at 23,000 cycles per second — far beyond the threshold of human perception. The result is perfectly smooth, eye-friendly dimming without the harsh flicker associated with lower-quality dimmers. The constant voltage output circuit ensures your LEDs always receive stable, clean power.
Important Notes
- Output is constant voltage, not constant current. The LED load connected to the output must include resistance current-limiting strips, groups, or panels.
- Slight color variation from product images may occur due to screen differences.
- Allow ±1 mm – 1 cm measurement tolerance due to manual measurement.
Package Includes
- 1 × PWM Touch Dimming Driver Board

Frequently Asked Questions
Q: What types of LED lights are compatible with this PWM touch dimming driver module?
A: This dimming driver module is compatible with DC LED strips, COB (Chip-on-Board) light strips, LED light bars, and LED light panels that use resistance current-limiting designs. It is not suitable for constant-current LED drivers or AC-powered lights. Always ensure your LED load does not exceed 5A.
Q: Does the touch dimming module work at both 5V and 24V?
A: Yes! The module accepts any DC input voltage between 5V and 24V. The output voltage equals the input voltage (pass-through constant voltage), so it is fully flexible across the supported range — ideal for 5V, 12V, or 24V LED systems.
Q: Will the LED strip flicker when dimmed with this PWM module?
A: No. This module operates at a switching frequency of 23 kHz (230,000 Hz), which is far above the human visible flicker threshold. The result is perfectly smooth, eye-friendly dimming with no perceptible flicker, making it safe and comfortable for long-duration use.
Q: Does it remember my brightness setting after a power outage?
A: Yes. The module features a memory function that stores the last active brightness level. When power is restored, it returns to that saved brightness state automatically — no need to readjust each time.
