NDR-75-48 is a 48V 1.6A 76.8W slim line DIN rail power supply aimed at powering devices that are intended to be used in a domes¬tic envi¬ron¬ment. The units are encased in a 32mm wide metal case, designed to be installed on TS-35/7.5 or TS-35/15 mounting rails. NDR-75-48 has a full range 90-264VAC input and is designed without a built-in fan; with 89% efficiency and cooling by free air convection it can operate at ambient temperatures between -20°C and 70°C. Other functions include short circuit, over load, over voltage and over temperature protections and front panel DC voltage adjustment. Safety regulations include UL, CUL, CB, TUV and CE; the requirements of EN55022 Class B, for EMI are also followed.
