Description
Product Resume
Welcome to use LED driver series by Sure Electronics. This product is constant current and step-down DC/DC converter. Featuring under voltage lock out (UVLO), over temperature protection, LED open-circuited protection and LED short-circuited protection.
This driver features small size, high efficiency, stability, long service time and easy installation. LED dimming can be controlled via an extra pulse width modulation (PWM) through EN pin.
