The BUCK constant current power supplies also kown as step down converters are charachterized by high operating ranges that are not subject to the number of connected illuminants (LEDs). Example: You can run a BUCK driver with 36V but with only one LEDs on the output side. The BUCK adjusts the volatge very efficiant and avoid overheating by autom. shut down to save the components. This is why we are able to offer this product for low prices because we can use FR4 PCB material instead of aluminium.

The Driver can also be used with our PWM dimmer. The minus pad of the dimmer has to be connected to the PWM pad of the driver. You also need to connect a 2K-10K resistor (1/4W) to the output channel of the dimmer. The driver expects a high-signal for 100% output so the brightness process is inverted. When the dimmer is on 0%, the driver will switch on 100%. Please note that the driver should only be dimmed down to 10% only. Below 10% we can't guarantee a flicker-free dimming process. You will find a schematic drawing in the datasheet.

Converting and quality are on highest levels. Connecting is vey easy too because the soldering pads are clearly defined by inscriptions. Please read below the further features of this powerful little helper.
