Details
Meanwell LDB-350L is DC-DC buck-boost glue filling constant current LED driver with 350mA2-40VDC95-240V±5%150mVp-p1000KHz75VDC9-36VDC89.00%91.00%1100mA%520mA2mA (Vin 24VDC). The product provides 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-350L is able to fit the electromagnetic compatibility requirements of EN55015 lighting without the need for additional electromagnetic interference suppression components. As to glue filling package, Meanwell LDB-350L is ideal 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.
