DLHR - 定电流 LED驱动器
产品说明 :
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.功能说明 :
- For 48V LED track light application
- Efficiency up to 95%
- Constant current output up to 1A
- Wide input and output voltage range
- 3 in 1 dimming (dim-to-off)
- Short circuit and over temperature protection
- Internal SMD technology
- UL 94V-0 package material
