APPLICATIONS
KC24W-XXXK series is a high-power
LED driver design for the step-down constant
current source. With high efficiency, wide
input voltage range, high-temperature
environment, functional and so on.
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.
