New 12V and 24V power supplies for the lower performance ranges up to 30W have been developed by the Siemens Industry Automation Division. The new Sitop PSU100C units of the Sitop compact product line feature a slim-line, space-saving design with a wide-range input for single-phase AC and DC networks. One of their main characteristics is low energy consumption – for example due to no-load losses and high efficiency even in partial-load operation.
