Details
Meanwell LDC-55 Series is 55W AC/DC mode Linear LED driver highlighting constant power output. The entire series could operate from 180~295 V AC. Meanwhile, the output current can be adjusted between 500mA to 1600mA. The efficiency reaches high up to 90% under the no fan design, Additionally, LDC-55 is able to work for -25℃~+80℃ case temperature under free air convection. the product is also equipped with various function options such as dimming methodologies. Considering its longevity, high efficiency, and excellent reliability, Meanwell LDC-55 Series provides optimal design flexibility for LED lighting system.
