DIN rail switching power supplies for low wattage applications

March 2007 Electrical Power & Protection

Mean Well has announced the introduction of new slim type DIN rail switching power supplies, MDR-40(40 W) and MDR-60(60 W) series, for the fast growing demand of low wattage DIN rail applications. These Class I models (with F.G.) are enclosed with fully isolated plastic case to prevent users from hazardous shock. The design of 40 mm in width complies with the slim trend that the precious space on the industrial rail inside the control cabinet can be saved effectively. Featuring up to 88% of efficiency, MDR-40 and 60 can be cooled by only free air convection up to 70°C that significantly increase the reliability and lifetime of the power supply. Another important feature of these slim DIN rail power are their low no load power consumption (<0,75 W). This unique characteristic in the market can significantly expand the application beyond just heavy industrial field, but can also be implied to datacom or IT applications with energy saving concern and to obey the anticipated government laws in the near future.

Short circuit protection, overload protection, overvoltage protection, and the DC OK relay contact for monitoring the status of PSU are standard functions for the MDR-40 and 60 series. Typical applications include factory automation, process control, electro-mechanical industry, datacom, and IT.
