Compact 24 volt power supplies with high performance but low space requirements

28.11.2008
Siemens's Industry Automation Division has added a new compact 40 ampere basic unit to its Sitop modular power supply series.

It is only 150 millimeters wide, which is 90 millimeters narrower than the previous unit. The 20 ampere power supply has also been renewed and is only 70 millimeters wide.


The two Sitop PSU300M standard mounting rail power supplies for connection to 3-phase 400-500 volt AC networks now have a wider range input (from 320 to 575 volt AC) than previous versions. This enables them to be used in almost all the world's 3-phase networks, and they provide a reliable 24 volt supply even when there are large deviations in the voltage supply. The user now simply evaluates the "DC 24 V OK" operating mode via the new, integrated dry signaling contact.

The new 40 ampere power supply is a substantial improvement on the previous model. Apart from its small dimensions, the power unit now supplies 60 amperes for five seconds, so it can easily switch on even terminal equipment with high starting currents. Its efficiency of up to 93 percent reduces energy consumption and heat build-up in the control cabinet

Like all Sitop basic units in the modular series, the new Sitop PSU300M standard mounting rail power supplies also have rugged metal enclosures. They can provide up to three times the rated current to meet short-term peak power demands. Moreover, the short-circuit response can be set with the options: latching shutdown or constant current with automatic re-ramp up to the output voltage. Used in combination with Sitop add-on modules, comprehensive protection can be achieved against primary and secondary disturbances.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
