Details
Meanwell LDB-L Series is DC-DC buck-boost glue filling constant current LED driver. The entire series has a variety of output currents of 300mA/350mA/500mA/600mA to choose from. At the same time, it features ultra-wide input, output voltage, and can be driven normally regardless of the voltage difference between output/input voltage. With built-in EMI filter, LDB-L can meet the electromagnetic compatibility requirements of EN55015 lighting without the need for additional electromagnetic interference suppression components. Thanks to glue filling package, Meanwell LDB-L Series is suitable for harsh environment applications with high dust/humidity such as street lights, street lights, landscape lights, tunnel lights, household lighting, backlights and other LED lighting modules.
