The slim power supply for control boxes

SITOP compact was developed to be an extremely space-saving power supply for the lower power range. It is especially suited to distributed applications in control boxes and in small control cabinets. Its high efficiency over the entire load range and low no-load loss make it exceptionally efficient. It is ideal for applications that are often in standby mode.

Compact power supplies – for the lower performance range

The SITOP PSU100C stabilized power supplies of the SITOP compact product line have an extremely slim line design that marks them out for distributed applications.

Extremely efficient in saving space and energy ...

... and optimal for use incontrol boxes

With a width of just 22.5 to 52.5 mm, SITOP PSU100C requires up to 1/3 less space on the mounting rail than comparable devices. Another convincing feature of these 12 V and 24 V power supplies is their high efficiency across the entire load range. Power loss is extremely low even during no-load operation – ideal, for example, for the efficient supply of machinery and equipment that are often in stand-by mode. Up to 35% of energy can be saved.


The 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 UPSredundancy and selectivity modules.
