Slimline Single Phase Power Supply

ALTECH’s slim type DIN rail switching power supply, PS-S Series designed for the fast growing demand of
low wattage DIN rail applications. These 10W to 100W models are enclosed with fully isolated plastic case
to prevent users from hazardous shock. The design complies with the slim trend that the precious space on
the industrial rail can be saved effectively. Featuring up to 84% of efficiency, this series is 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 PS-S Series is its low power consumption (<0.75W). This unique characteristic can
significantly expand the application of PS-S series beyond just heavy industrial field, but can also be implied
to datacom or IT applications that require green power to save the energy and to obey the anticipated
government laws in the near future!

Short circuit protection, overload protection, over voltage protection, and the DC OK signal for monitoring the
status of power supply are standard functions for the PS-S Series. Typical applications includes factory automation,
process control, electro-mechanical industry, datacom and IT.
