Details
Meanwell NLDD-1200H is a 60W DC/DC step-down LED driver with 1200mA6-52VDC±5% at 48VDC input350mVp-p200KHz10~56VDC (59VDC Max.)1200mA5mA100~1KHz. The unit is designed in compact size and constant current output. At the same time, it converts 48V DC input voltage into constant current output and directly drives the LED module. Moreover, the efficiency reaches high up to 96%. Based on 94V-0 flame retardant plastic case, fully-potted silicone enhancing heat dissipation, this makes the unit possible 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. As a result of its longevity, high reliability and low cost, Meanwell NLDD-1200H is an ideal solution for driving illumination LED such as commercial track lamps or indoor lighting fixtures such as offices and classrooms.
