The output voltage of the new PSU100S power supplies is adjustable over a wide range from 24 to 28 V with the 24 V power supplies and from 12 to 15.5 V with the 12 V models. All devices can supply 1.5 times the rated current for five seconds per minute, to ensure problem-free starting for loads that draw a high current. The 24 V versions even supply 120 percent rated current at ambient temperatures up to 45 degrees Celsius.
The power supplies of the Sitop smart product line are designed for standard requirements in automated machines and plants. As for the currently available Sitop smart power supplies, the new single-phase Sitop PSU100S power supplies also feature a signaling contact for evaluating the operating status "Output voltage OK". With widths of only 32.5 mm (24 V/ 2.5 A), 50 mm (24 V/ 5 A and 12 V/ 7 A) and 70 mm (24 V/ 10 A and 12 V/ 14 A) and no sideways clearance requirements, the power supplies require less space on the mounting rail. These slim power supplies feature automatic range switching for connection to 120 V and 230 V supply systems worldwide. A radio suppression level of Class B and line harmonic limiting also permit use on the public low-voltage grid. Certification for GL (Germanische Lloyd) for shipbuilding and ATEX (Atmosphère Explosive) for hazardous environments ensure that the power supplies can be used universally.
The new Siemens power supplies can be used at ambient temperatures from -10 and +70 degrees Celsius and are characterized by a high degree of efficiency of up to 90 percent, which ensures only minimal heat generation in the control cabinet. For protection against faults in the network or in the output circuit, Sitop add-on modules offer enhanced protection for the 24 V power supplies, for example, through conversion to an uninterruptible DC power supply or for selectivity in 24 V feeders.

Different eras of civilization are defined by the discovery of new materials, as new materials drive new capabilities. And yet, identifying the best material...
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
