Dimmable LED Power Supply
LEADSUN has developed a series dimmable constant current power supplies which are designed to power various LED luminaires. They are protected against short current and over load. Integrated with PWM controller and our patent pending SCENE MATCH technology, they are allowed to dim LED luminaires to 4 lumens levels (100%,75%,50%,25%) by flicking a common light switch. User can easily build their light system in high efficient and low cost by using this high performance power supply.
