■ Description

LDC-55 series is a 55W AC/DC LED driver featuring the Constant Power mode output. LDC-55

operates from 180~295VAC and output current can be adjust between 500mA to 1600mA.

Thanks to the efficiency up to 90%, with the fanless design, the entire series is able to operate

for -25 ~+80 case temperature under free air convection.LDC-55 is equipped with various℃℃

function options, such as dimming methodologies, so as to provide the optimal design flexibility

for LED lighting system.
