DC LED Constant Current Step Down Module Buck Converter Constant Current LED Driver 0-1.5A LED PWM Dimming Driver
Product Description
This module is a step-down constant current source specially designed for high-power LED drivers. It has an ultra-wide input and output voltage range, uses a constant current mode output, and supports analog dimming, PWM dimming, and remote on/off control functions. The efficiency is as high as 95%. It has perfect short-circuit protection, overheating protection, LED open circuit protection functions, and the protection is comprehensive and reliable. The onboard high-precision multi-turn potentiometer is convenient for users to adjust the working current of the LED in real time, that is, to adjust the brightness. This module can drive a single 1W, 3W or multiple series and parallel LEDs, without any technical requirements for users, no external components, plug and play, easy to use. It can be widely used in various environments such as landscape LED lighting, specially controlled LED lighting, LED backlight, household LED lighting, automotive LED lighting, electric vehicle LED lighting, and motorcycle LED lighting drive.
