DIN-rail switchers satisfy low-power demands

Sunpower has a new slimline DIN-rail switching power supply, the MDR-20 Series, for the fast growing demand of low wattage DIN rail applications. These 15-24W Class I models are enclosed within a fully isolated plastic case to prevent user contact and the risk of hazardous shock. The design of 22.5mm in width complies with the slim trend so that it effectively saves precious space on the industrial rail.

Featuring up to 84% efficiency this series can be cooled using only free air convection at temperatures up to 70C, therefore significantly increasing the reliability and lifetime of the power supply.

Another important feature of MDR-20 is its low no load power consumption (less than 0.75W), which expands the application of MDR-20 beyond the heavy industry field DIN products are often associated with into datacomms or IT applications that require green power to save energy and to be in line with likely future legislation.

Other standard functions include short circuit protection, overload protection, overvoltage protection and DC OK signal for monitoring the status of the power supply.
