APPLICATIONS
The KC24H Series is a 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. 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.

Note:
1. The types without suffix, such as KC24H-1000 are eight-pin products without analogue dimming+PWM dimming function.
2. The types with suffix X1,such as KC24H-1000X1 are nine-pin products with analogue dimming function only.
3. The types with suffix X2,such as KC24H-1000X2 are nine-pin products with PWM dimming function only.
4. The types with suffix X3,such as KC24H-1000X3 are ten-pin products with analogue dimming+PWM dimming function.
