LED Driver
The LEDW10_24 is a high-power LED driver designed for the step-down constant
current source. With high efficiency, wide input voltage range, high-temperature
environment, functional and so on. Contains a PWM dimming, analog dimming and
remote shutdown capabilities.
It can be widely used in backlight and 12V, 24V, 36V landscape lighting, special
lighting controls, commercial lighting, street lighting, home lighting, automotive
lighting and other lighting systems. Use of lead type package, allowing customers
to use more convenient.
