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: 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...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
