Details
Meanwell LDH-45B-700 is DC-DC Step-Up LED driver with 700mA21-64VDC36-64VDC75V44.8W1.2Vp-p24VDC18-32VDC95.00%2A. The model highlights constant current output with rated current 700mA. It also 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. Since the efficiency reaches high to 95%, and works at -40℃~+70℃ under natural air cooling and heat dissipation conditions. LDH-45B-700 adopts internal glue filling method, enhancing the heat dissipation effect with high waterproof and dustproof capabilities. Furthermore, 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 suppression components. Moreover, it is supplied with various function options such as short-circuit protection, overvoltage protection, input undervoltage protection. As a result of its longevity, high efficiency and excellent quality, Meanwell LDH-45B-700 is an ideally suitable solution for optimal design flexibility for LED lighting system like street lights, landscape lights, tunnel lights, household lighting, etc.
