LED Soft-Start Controller Module – Light Strip Driver 5/12/20/30V

Smooth Gradual LED Lighting Control — Slow-Start & Slow-Stop Driver Module

Transform your LED lighting setup with this intelligent LED Soft-Start & Soft-Stop Controller Module. Designed for LED strips and lighting systems running on 5V, 12V, 20V, or 30V, this compact driver module creates a smooth, gradual fade-in and fade-out effect every time your lights power on or off — eliminating harsh instant switching for a polished, professional look.

Key Features

• Wide Voltage Compatibility: Supports 5V, 12V, 20V, and 30V LED systems — versatile enough for home, commercial, and DIY lighting projects.
• Max Power: Handles up to 100W, suitable for a broad range of LED strips and driver setups.
• Adjustable Brightness: The onboard red switch allows precise brightness adjustment. Settings are saved to memory, so your preferred brightness level is automatically restored the next time the lights come on.
• Configurable Slow-On & Slow-Off Timing: Use the DIP switch to set the fade-in and fade-out duration independently — choose from 1, 2, 3, 5, 7, 9, 12, or 15 seconds to match your environment perfectly.
• Adjustable Buffer Time: Set an additional buffer/delay time via the DIP switch — options include 1, 3, 5, 7, 9, 12, 15, or 20 seconds for total timing flexibility.
• External Button Support: Connect an external button to manually control the on/off state of your lights.
• Power-On Behavior Selection: The "S" solder point lets you choose startup behavior:
  • S not soldered (default): Light turns on automatically when power is applied.
  • S short-circuited: Light does NOT turn on automatically — an external switch is required to activate.
• Made in Mainland China.

Frequently Asked Questions

Q: What LED systems is this slow-start LED controller module compatible with?

A: This LED soft-start and soft-stop controller is compatible with LED strip systems operating at 5V, 12V, 20V, or 30V DC, with a maximum power load of 100W. It works with a wide range of single-color LED strips and lighting drivers commonly used in home and commercial installations.

Q: How do I set the fade-in and fade-out timing on this LED driver module?

A: The fade-in (slow-on) and fade-out (slow-off) times are configured independently using the onboard DIP switches. You can select from preset durations of 1, 2, 3, 5, 7, 9, 12, or 15 seconds for each direction, allowing you to fine-tune the gradual transition to suit your space and preference.

Q: Will the LED light turn on automatically when power is supplied?

A: By default (with the "S" solder point left open), the LED light will turn on automatically with a smooth fade-in as soon as power is applied. If you prefer manual control, short-circuit the "S" solder point — the light will then remain off on power-up until activated by an external switch or button.

Q: Does this controller save my brightness settings?

A: Yes! The onboard red brightness adjustment switch features memory functionality. Once you set your desired brightness level, the controller stores it so your LEDs return to that exact brightness the next time they are switched on — no need to readjust each time.
