Because of their high reliability, Siemens SITOP power supply units are globally recognized for their high reliability and for their coping with critical network conditions. The full range of switched-mode power supply units provides a controlled 24 V DC power supply and other voltages. The unique spectrum of DC UPS and addon modules extends the power supply range to protect the 24 V supply against mains problems and problems on the DC side. SITOP is also top-notch when it comes to efficiency, thanks to an efficiency rating of up to 95%. For example, the availibility of tools to make product selection and ordering quick and easy, and comprehensive support from Siemens and E.B. Horsman for your design processes. Further, complete integration in Totally Integrated Automation and the TIA Portal via PROFINET gives you unique opportunities for engineering and diagnostics.

SITOP Compact:

The Slim Power Supply For Control Boxes

Thanks to the extremely space-saving slim design, the power supply series for the lower performance range is especially suited to be integrated into distributed applications in control boxes or in small control cabinets. The power supplies are characterized by their low power loss over the entire load range. Power loss is extremely low even during no-load operation, which is why they are ideal, for example, for the efficient supply of machinery and equipment that are often in stand-by mode.

The SITOP PSU100C switched-mode power supplies have a wide-range input for AC and DC networks, with plug-in terminals allowing a simple electrical connection. The wide range of temperatures together with comprehensive certifications offer universal application options combined with the proven SITOP reliability.

To further increase the availability, the SITOP compact power supply units can be combined with DC UPS and redundancy modules.

Cost-Effective Basic Power Supply

The new range of power supplies is designed for standard requirements in industrial environments and offers all important functions at a favorable price, of course without compromising quality and the proverbial SITOP reliability. The wide-range input with manual switchover supports connection to a wide range of 1-phase supply systems. Thanks to the narrow width, the primary switched-mode regulators require little space on the DIN rail and can be easily integrated. Short-circuit and overload protection as well as UL approval for export ensure problem-free use.
