Description
12V DC TRIAC Dimmable LED Driver – 20W (Model DR-CV-20)
The HUEUC DR-CV-20 12V TRIAC dimmable LED driver converts 180–240V AC mains power into a stable 12V DC constant-voltage supply for compatible LED strip lights, COB LED strips, downlights and low-voltage LED fittings. Designed for smaller dimmable lighting installations, it is ideal for kitchen cupboards, shelving, display cabinets, furniture lighting, alcoves, media units and architectural feature lighting. Its mains-side TRIAC dimming, compact enclosed housing, high power factor and SELV output make it a practical, professional solution wherever smooth control of 12V LED lighting is required.
The driver is installed between the mains supply and the 12V LED lighting. When connected to a suitable LED-rated TRIAC wall dimmer, the brightness of the connected lighting can be adjusted without requiring a separate low-voltage dimming controller after the driver.
Key Features & Benefits
- TRIAC mains dimmable – allows compatible 12V LED lighting to be controlled from a suitable mains-voltage LED dimmer.
- Wide dimming range – designed to provide approximately 5–100% brightness adjustment, depending on the dimmer and connected LED load.
- Stable 12V constant-voltage output – suitable for compatible LED strips, modules, downlights and other 12V fittings.
- Compact enclosed design – easy to conceal inside cupboards, furniture, ceiling voids or service spaces.
- High power factor – power factor greater than 0.95 for efficient, professional-quality operation.
- SELV output – provides Safety Extra Low Voltage power for compatible 12V LED lighting.
- Class II double insulated – no earth connection is required.
- IP20 indoor construction – designed for installation in dry indoor locations.
Typical Applications
- Kitchen under-cabinet LED lighting
- Furniture, wardrobe and shelving illumination
- Display cabinets and retail displays
- Media units and feature lighting
- Cove, pelmet and alcove lighting
- Small COB LED strip installations
- Compatible recessed downlights and low-voltage fittings
- Domestic, hospitality and commercial interior lighting
Dimming Compatibility
The DR-CV-20 is dimmed through its 180–240V AC mains input and is designed for use with a compatible LED-rated TRIAC mains dimmer.
For the best performance, we recommend using a good-quality trailing-edge electronic LED dimmer. The minimum achievable brightness and overall dimming performance may vary depending on the dimmer, the connected LED products and the total load.
This driver is not designed for use with a separate 0–10V dimming signal.
Simple Dimming Summary
Install a compatible LED-rated TRIAC dimmer on the mains input side of the driver. The driver then converts the dimmed mains supply into a regulated 12V DC output for the connected LED lighting.
Installation Guidance
- Install the driver in a dry, suitably ventilated indoor location.
- Do not cover the housing with insulation or restrict airflow around the unit.
- Check that the total wattage of the connected LED lighting remains within the permitted output load.
- Allow some spare capacity rather than operating continuously at the absolute maximum load.
- Mains wiring should be completed by a suitably competent person.
Summary
The DR-CV-20 12V TRIAC dimmable LED driver is a compact and reliable solution for smaller low-voltage lighting installations requiring convenient wall-switch dimming. Its regulated output, wide dimming capability, high power factor, SELV classification and double-insulated enclosed housing make it ideal for kitchen lighting, furniture, displays, shelves and other professional indoor LED installations.
