Powerful standard 24V power supply for three-phase networks

16.04.2010
The Siemens Industry Automation Division has expanded its Sitop smart series of power supplies with a 24V unit with 3-phase connection. The Sitop PSU300S is designed for standard regulated 24V direct voltage requirements for machinery and plants.

The new power supply unit with adjustable output voltage from 24 to 28 volts features a wide-range input from 340 to 550 V AC and supplies 20-ampere rated current. With an overall width of just 100 millimeters and no need to calculate lateral clearance for installation, the primary-switched power supply only requires minimum space on the DIN rail.


The high efficiency of more than 91 percent ensures minimum loss of energy and low heat generation in the control cabinet. The new unitsupplies 1.5 times the rated current up to five seconds long for starting up loads with high power requirements. Sitop PSU300S supplies 20 amperes of rated current for ambient temperatures of 0 to 60 degrees and can be operated up to 70 degrees with derating. At temperatures of less than 45 degrees, the stabilized power supply continuously provides up to 20 percent overload current.

With the 3-phase wide range input of 340 to 550 V AC and international certification, the new Sitop PSU300S can be used all over the world. Even with extreme voltage fluctuations, the unit steadily provides 24 volts. Additional Sitop modules are available for increased protection against disturbances from the external network or for 24V circuits, for configuring a redundant or uninterruptible DC power supply, or for selectivity in 24V feeders for example. The operating state of the "24 V DC o.k." can be evaluated by a controller using an integrated floating signaling contact.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
