12V DC Dimmable LED Driver – 20W (Model DR-CV-20)
The DR-CV-20 is a compact and reliable 12V DC constant-voltage dimmable LED driver, designed to power low-voltage LED lighting while allowing smooth, flicker-free brightness control. It is ideal for use with 12V LED strip lighting, LED modules, and low-voltage LED fittings in domestic, leisure and commercial environments.
This driver converts mains power to a stable 12V DC output, ensuring safe operation and consistent performance of your LED lighting. When paired with a compatible dimmer, it allows you to adjust light levels easily to create the desired atmosphere.
Key Benefits
- Smooth Dimming Performance – Designed for flicker-free dimming with compatible dimmer switches
- Stable 12V DC Output – Constant-voltage design protects LEDs and ensures even brightness
- Compact & Discreet – Easy to conceal in cabinets, ceilings or furniture
- Reliable & Efficient – Ideal for everyday LED lighting installations
- Indoor Rated (IP20) – Suitable for dry, indoor locations
Typical Applications
- LED strip lighting (under cabinets, shelving, coving)
- Accent and mood lighting in kitchens, bedrooms and living spaces
- Interior lighting in caravans, campervans and motorhomes (via inverter/mains supply)
- Display and feature lighting
- Any 12V LED installation requiring dimming control
Dimming Compatibility (Important)
This driver is dimmable via the mains input and is compatible with:
Trailing-edge (electronic / TRIAC) LED dimmers
It is not compatible with:
- Leading-edge dimmers
- 0–10V dimming systems
Simple Summary
Use a trailing-edge (electronic) LED dimmer for correct operation. Do not use leading-edge or 0–10V dimmers.
For the smoothest dimming and longest driver life:
- Use a quality LED-rated trailing-edge dimmer
- Avoid very low minimum loads
- Aim to run the driver at 20–100% of its rated capacity rather than right at the limit
Summary
The DR-CV-20 is an excellent choice where reliable 12V power and smooth dimming are required. Compact, efficient and easy to integrate, it’s ideal for LED strip lighting and low-voltage LED installations where professional performance matters
