LEDT16_24 Series
Constant current power LED Driver - Wide Input - Non-Isolated & Regulated
LED Driver
The LED16_24 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 con-
trol, and SMD package which facilitates the installation.
SMD package, simple and
convenient
High efficiency up to 96%
Short Circuit Protection (SCP)
