DLHR - Constant Current LED Driver, Constant Current and Step-Down DC/DC converter : DLHR

DC/DC converter-Constant Current LED Driver

DLHR series is a high efficiency, constant current and step-down DC/DC Converter. The LED driver operates an input voltage from 12Vdc to 56Vdc and provides an externally adjustable output current up to 1000mA and an output power up to 45 watts. It is able to include the function of over temperature protection (OTP), over current protection (OCP), and 3 in 1 dimming (dim-to-off) comprised by PWM generator, 0-10Vdc interface and resistor potentiometer. Especially its outward appearance design is suitable for LED track light application.
