External Low-Power LED Series

Main features

        1, Overcurrent protection, short circuit protection, open circuit protection, over-temperature protection; safety isolation, anti-lightning.

        2, With EMC, anti-electromagnetic interference.

        3, With the soft-start function.

        4, The precise constant current output, not with the input voltage, ambient temperature and working time and changes

        5, Low ripple, to ensure that the LED used in security, stability, improve the efficiency of the LED light, reduce LED light fades.

        6, High conversion efficiency not only saves energy, power itself can reduce fever, the drive power long-life.

        7, Using genuine high quality components, and can work continuously for a long time, long life.

        8, Using the global voltage range input voltage is 86 ~ 265V change, able to constantly work.
