DANUBE http://www.danube.com.tw 2012/07/19 9-1 SLE-24 SERIES Constant Current LED Driver

FEATURES

 EFFICIENCY UP TO 95%  CONSTANT CURRENT LED DRIVER  WIDE INPUT AND OUTPUT VOLTAGE RANGE  INPUT VOLTAGE UP TO 36V  PWM DIMMING CONTROL  SHORT CIRCUIT AND OVERTEMPERATURE PROTECTED  INTERNAL SMD TECHNOLOGY  FULLY ISOLATED PLASTIC CASE WITH IP67 LEVEL  UL 94V-0 PACKAGE MATERIAL  RoHS COMPLIANT  3 YEARS WARRANTY  DESCRIPTION SLE-24 series is a high efficiency, constant current and step-down DC/DC converter. The LED DRIVER operates from an input voltage 9Vdc to 36Vdc and provides an externally adjustable output current of up to 700mA and output power up to 22 watts. It is able to include the function of Over temperature protection(OTP), Over current protection(OCP), PWM/Digital Dimming and ON/OFF. The device can extensively be used for Landscape illumination, Special illumination, Back light source, Commercial illumination, Street light illumination, Home use illumination and Automobile illumination etc.  SELECTION GUIDE MODEL NUMBER INPUT NOMINAL VOLTAGE (VDC) INPUT VOLTAGE RANGE (VDC) OUTPUT VOLTAGE RANGE (VDC) OUTPUT CURRENT RANGE (mA) DIMMING CONTROL EFF (%,MAX) SLE-24-0.30D(W) 24 9-36 2-32 0-300 PWM 95 SLE-24-0.35D(W) 24 9-36 2-32 0-350 PWM 95 SLE-24-0.50D(W) 24 9-36 2-32 0-500 PWM 95 SLE-24-0.60D(W) 24 9-36 2-32 0-600 PWM 95 SLE-24-0.70D(W) 24 9-36 2-32 0-700 PWM 95 SLE-24-0.30S 24 9-32 2-28 0-300 PWM 95 SLE-24-0.35S 24 9-32 2-28 0-350 PWM 95 SLE-24-0.50S 24 9-32 2-28 0-500 PWM 95 SLE-24-0.60S 24 9-32 2-28 0-600 PWM 95 SLE-24-0.70S 24 9-32 2-28 0-700 PWM 95
