Details

Meanwell NLDD-500H is a 60W DC/DC step-down LED driver with 500mA6-52VDC±5% at 48VDC input150mVp-p200KHz10~56VDC (59VDC Max.)490mA5mA100~1KHz. The item features constant current output in compact size. And It converts 48V DC input voltage into constant current output and directly drives the LED module. Meanwhile, the efficiency reaches high up to 96%. Based on 94V-0 flame retardant plastic case, fully-potted silicone enhancing heat dissipation, this allows the unit to meet 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. Thanks to its longevity, high reliability and low cost, Meanwell NLDD-500H is an ideal solution for driving illumination LED such as commercial track lamps or indoor lighting fixtures such as offices and classrooms.
