After the launch of the DC/DC buck type LED converters (LDD series), MEAN WELL further introduced the new boost type DC/DC constant current LED drivers~LDH-45 series. The new drivers possess 9~18VDC input for LDH-45A-X models and 18~32VDC input for LDH-45B-X models. Both series feature with 350mA/500mA/700mA/1050mA output current. In addition, LDH-45 series have built-in PWM and analog dimming function; thus, the ON/OFF remote control and the output current adjustment can be realized by connecting the external PWM signal or 0.25~1.3VDC analog voltage, which can satisfy the demands of various energy-saving dimming designs for lighting fixtures.

LDH-45 series possesses up to 95% of extremely high efficiency and can operate between -40~+70°C of ambient temperature by only free air convection. All series are potted for providing better ability of heat dissipation, anti-dust, and anti-moisture. Furthermore, they offer two kinds of input/ output packages like pin style or wire style for selection. Built-in EMI filter, these LED drivers comply with EMI requirements per EN55015 lighting regulation without connecting any external EMI restraint components. Other standard functions include short circuit, over voltage, and input under voltage protections. Suitable applications include street lighting, landscape lighting, tunnel lighting, household lighting, and all kinds of off-grid LED garden lights or LED street lights that powered by solar charger.
