Details
Meanwell NLDD-H Series is a 60W DC/DC step-down LED driver featuring constant current output designed in compact size. The entire series converts 48V DC input voltage into constant current output and directly drives the LED module. NLDD-H is available in a variety of output currents, including 350/500/700/1050/1200/1400 mA. Moreover, the efficiency reaches high up to 96%. With 94V-0 flame retardant plastic case, fully-potted silicone enhancing heat dissipation, this allows the products to fit for class Ш or DC bus lighting applications. LDD, LDB, LDH series are all DC-DC constant current output LED drivers, LDD is step-down type, LDH is step-up type, and LDB is buck-boost type model. Considering its longevity, high reliability and low cost, Meanwell NLDD-H Series serves as an ideal solution for driving illumination LED such as commercial track lamps or indoor lighting fixtures such as offices and classrooms.
