Compact, efficient and powerful – these are the three key features of the new three-phase Sitop PSU300S power supplies and the single phase Sitop PSU100C device versions. The narrow footprint of the power supplies only requires a small mounting area. Because of their high efficiency, the new models consume less energy and generate less waste heat than comparable devices on the market.
The Siemens Sitop Smart power supply line has been extended by two new versions of the Sitop PSU300S power supply for three-phase mains connection. To complement to the already available power supply with a 20A rated current, the new versions offer 10 and 40A rated output currents. The 10A power supply comes in a metal enclosure just 90mm wide.
The 40A device requires a 145mm space on a DIN rail. The compact size is achieved through the high efficiency of over 91 percent, which reduces the development of heat and makes a voluminous heat sink superfluous. The Sitop PSU300S power supplies are optimized for standard requirements in automated machines and plants which require a stabilized direct voltage of 24V. The high-performance power supplies can deliver 1.5 times the rated current for five seconds, such as during the start up of loads with a high current demand. An integrated signaling contact enables a controller to evaluate the operating state of the power supply as a "24V O.K." statement.
The power supplies can also be combined with redundancy modules, selectivity modules and DC UPS modules (uninterruptible direct current power supply). With their three-phase wide-range input for alternating current from 340 to 550V together with comprehensive certification for all standard applications, the PSU300S devices have been designed for use throughout the world.
Siemens has added three higher-output versions of the single phase Sitop PSU100C power supply to the Sitop Compact power supply line. The two 24V versions supply 2.5 and 4A rated output currents respectively, the 12V version has been designed to deliver a 6.5A rated output current. With overall widths of only 45 and 52.5mm, the new Sitop power supplies are especially suitable for decentralized use in the lower power range of up to 100W, such as installation in switch boxes and small control cabinets. Like all the models in the product line, the new DIN rail devices are characterized by high efficiency throughout the entire load range and low no-load losses of less than 1W. The wide-range input facilitates connection to single phase alternating current networks with voltages of 120 and 230V, or to direct voltage networks with voltages between 110 and 300V. Detachable clamp-type terminals allow the use of pre-assembled wiring and make it easy to exchange devices. The power supplies are suitable for universal use in an operational temperature range from -20 to +70 degrees Celsius.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
