DC-DC Constant Current Driver With DC 380V Input Constant Current mode output Driver on Board (DoB) Solution available Recessed lighting Plastic housing and Fully encapsolated Linear lighting Built-in PWM and Remote ON/OFF control DC house lighting system Protections:short circuit/over temperature Industrial lighting 5 years warranty Note Driver on board (DoB) solution is available, including circuit diagram and key : components such as Driver IC or choke,please contact MEANWELL for detail. ■ Description NHDD -40 series is a DC / DC LED driver. It operates from 360 ~ 400 VDC and offers constant current output. Thanks to the efficiency up to 95%, with the fanless design, the entire series is able to operate for -30 ℃ ~+90 ℃ case temperature under free air convection. In addition, NHDD is a particular design for DC 380V Bus lighting application which can be combination with green energy storage and also can be an intelligent lighting system. ■ Model Encoding NHDD - 40 - 100 W Output style(Blank: PIN style; W:wire style) Output current(100mA) Rated wattage Series name
