APPLICATIONS
The KC24RT is a series of step-down
constant current source designed for driving
high power LEDs. It features high efficiency,
wide input voltage range, high operating
temperature, PWM and analogue dimming,
remote ON/OFF control, and SMD package
which facilitates the installation. It is widely
used in LED illumination areas such as
decorative light, special control light,
backlight, commercial light, streetlight,
in-house light and car light, etc.
