MEAN WELL SDR-75 series has been widely exploited in various industrial systems that require high performance and slim design DIN rail power supplies. In order to satisfy the market demands more extensively, MEAN WELL unveils the new EDR-75 and NDR-75 series so as to provide the solutions for the projects in need of the economical 75W DIN rail power supplies. With the same dimension and unit width (32mm) of SDR-75 series, EDR-75 and NDR-75 are able to be installed on DIN rail TS-35/7.5 or TS-35/15. They are the ideal power supply models for the cabinets with a limited width.
EDR-75 and NDR-75 accepts the full range 90~264VAC at input and supplies 12V, 24V, and 48V DC voltages at output. These two series are designed without the built-in fan. Thanks to the efficiency up to 88.5% (EDR-75) and 89% (NDR-75), with the cooling by free air convection, they can operate under -20~+60°C (EDR-75) and -20~+70°C (NDR-75), respectively. Other functions comprise short circuit protection, overload protection (constant current limiting output), over voltage protection, over temperature protection, and front panel DC voltage adjustment. EDR-75 and NDR-75 are certified with UL/CUL/CB/TUV/CE safety regulation and observe EN61000-6-2, the heavy industry grade EMS (Electro Magnetic Susceptibility) standard. Regarding EMI (Electro Magnetic Interference), EN55022 Class A (EDR-75) and Class B(NDR-75) are followed, respectively. Suitable applications include industrial control system, semiconductor fabrication equipment, factory automation, electro-mechanical apparatus, and etc.
