SITOP compact

The slim power supply unit 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.
