Details
Meanwell LDH-45A-350 is DC-DC Step-Up LED driver with 350mA12-86VDC24-86VDC100V30.1W2.5Vp-p12VDC9-18VDC91.00%2.8A%. The product features constant current output. At the same time, it has built-in PWM and analog dimming functions, which can realize remote ON/OFF control and adjust output current through external PWM signals or 0.25~1.3VDC analog voltage to meet the diversified energy-saving dimming needs of the lamp system. As the work efficiency reaches high to 95%, and operates at -40℃~+70℃ under natural air cooling and heat dissipation conditions. LDH-45A-350 adopts internal glue filling method, enhancing the heat dissipation effect with high waterproof and dustproof capabilities. In addition, the input and output have two versions: plug-in type and outlet type, which is convenient for the selection of system design. With built-in EMI filter, the unit can fit the requirements of the EU EN55015 specification without additional electromagnetic interference (EMC) suppression components. What’s more, it is equipped with various function options such as short-circuit protection, overvoltage protection, input undervoltage protection. Thanks to its longevity, high efficiency and excellent quality, Meanwell LDH-45A-350 is an ideally suitable solution for optimal design flexibility for LED lighting system like street lights, landscape lights, tunnel lights, household lighting, and so on.
