Constant current power supplies

Diffusione luce offers for sale a complete range of constant current electronic power supplies for LED applications. To choose the right constant current power supply it is necessary to carry out this calculation: current absorbed by the LED spotlight x working voltage of the spotlight. Example: 0.350 A x 3.4 volts = 1.2 W (power absorbed by the spotlight). In this case, you must choose a power supply with an output power starting from 1.2W and a current of 0.350 A. Do not install power supplies with a minimum output power higher than the nominal power absorbed by the installed spotlight, for example: 1.2W and 350mA spotlight with power supply starting from 4w and 350mA -> wrong and broken LED diode. Different matter when LED spotlights are installed in series, in this case to calculate the power of the power supply it is necessary to add the power of the spotlights, example: 10 products of 1.2w and 350 mA = 12w 350mA -> necessary power supply with nominal power minimum 12w 350mA. Meanwell electronic ballasts with IP65/IP67 protection ratings are also available for outdoor applications.
