To provide solutions for projects in need of the economical 75W DIN rail power supplies, MEAN WELL has launched the EDR-75 and NDR-75 series. With the same dimension and unit width (32mm) of SDR-75 series, these power supplies can be installed on DIN rail TS-35/7.5 or TS-35/15. This makes the series suitable power supply models for cabinets with a limited width.

EDR-75 and NDR-75 accept the full range 90-264V AC at input and supplies 12, 24, and 48V DC voltages at output. These 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 from -20 to +60℃ (EDR-75) and from -20 to +70℃ (NDR-75), respectively. Other functions include short circuit protection, overload protection (constant current limiting output), over voltage protection, over temperature protection, and front panel DC voltage adjustment.

These power supplies 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 and electro-mechanical apparatus.
