ITEM NAME:5-35V LED Driver High Power 3W PWM Dimming DC to DC Step-Down Constant Current Product Description Description: 3W 5-35V DC LED Driver High Power PWM Dimming DC to DC Step-Down Buck Constant Current Driver Feature: Support PWM dimming, high level, low output, low output. The buck mode can ensure that the total voltage difference of the LED is less than the total voltage difference of the input voltage 2-3V. Ultra-small volume design, low noise, high safety. Use high-efficiency, low-consumption and stable chips to achieve energy saving and environmental protection Constant output current and low ripple. It ensures the safety and stability of the LED, improves the optical efficiency of the LED and reduces light attenuation. Specification: Product number: LED-3W Input range: DC 5-35V Product size: 35*20*12mm/1.38*0.79*0.47" Note: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2.
