LED Fade On Fade Off Slow Start Low Voltage Light with Driver Module LED Controller Dimming Slow Start _x000D_ _x000D_ Features: 1. Power ≤100W, compatible with 5-24V wide voltage range for diverse power environments 2. Supports S1 jumper setting: power-on without illumination, requires button press for activation—more energy-efficient 3. S2 supports either touch-sensitive or physical switch options for versatile control methods 4. Retains brightness memory after power loss; resumes at last setting upon restart for smarter operation 5. DIP switches adjust fade-in/fade-out duration with 8-step precision control over startup rhythm _x000D_ Parameter: Power Range: ≤100W Voltage: 5-24V External Button: Functions as on/off switch Brightness Adjustment: The red switch on the board adjusts brightness. Once set, brightness is memorized; subsequent turns on will use the last brightness setting. _x000D_ Product Usage: S1 Unshortened: Power-on gradually brightens and turns on the light S1 Shortened: Power-on does not turn on the light; external button is required for gradual brightening and turning on S2 Unsoldered: Tactile switch (light touch button switch) S2 Shorted: Physical switch (toggle switch, knife switch) Fade-out time: Configurable via DIP switches to 1s, 3s, 5s, 7s, 9s, 12s, 15s, 20s Fade-in time: Configurable via DIP switches to 1s, 2s, 3s, 5s, 7s, 9s, 12s, 15s _x000D_ Package include: 1 x 100W LED Dimming Module with Slow Start/Stop Function for Low Voltage LED Strip Lighting Driver Module _x000D_ _x000D_
