12V constant voltage LED drivers

12V constant voltage LED drivers for 12V LED strip lights and other 12V LED installations. Available in a range of wattages from leading brands including Mean Well, Helvar and POS.

How to choose the right driver

Select a driver rated approximately 20–30% higher than your total LED load. For example, if you're installing 2 metres of 12V LED strip with 12W/m consumption (12W × 2m = 24W total), choose at least a 30W constant voltage driver. The driver may be larger than this minimum recommendation, but never smaller than your calculated requirement.

Available options

  • Wattages from 15W to 75W and beyond
  • Waterproof IP67-rated models for outdoor and wet locations
  • Dimmable versions with TRIAC and transistor dimming compatibility
  • Slim-profile designs for compact installations

Different dimming methods affect the choice of transformer.

Basic converters work on/off, ie with a normal light switch, lighting and turning off LED-Ribbon. If you dim LED-Ribbon, this must be taken into account when choosing a standard voltage source. RF and RF WIFI for dimming Choose also 12v basic transformer (For dimming occurs in the receiver transformer and LED-Between the ribbon, on the secondary side, the transformer itself is not usually dimmed). If you dim 12v LED-your tape triac or 1-10v so select Triac or 1-10V standard voltage source. Traditional fixed wall mimics such as Shneider Exxact UN400LED Triac dimmable 12V power supply. Outdoor use moisture protected 12V LED-In transformers.
