© Siemens AG 2011 SITOP compact power supply Extremely efficient in saving space and energy Brochure · April 2011 Space savings of up to 33% Energy savings of up to 35% SITOP compact Answers for industry. © Siemens AG 2011 Slimline power supply unit for control boxes The SITOP PSU100C stabilized power supplies of the SITOP compact product line for the low-end performance range have an extremely slimline design that marks them out for distributed applications, e.g. installation in control boxes or small control cabinets. With a width of just 22.5 to 52.5 mm, the power supply units require 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. And because the power losses are also extremely low, even in no-load operation, users save up to 35% of energy. The wide-range input enables problem-free connection to single-phase AC networks as well as to DC networks. The plug-in terminals also ensure user-friendly connection.

In operation, they are mainly run only within a load range of 30% to 70% of rated power – dependent on the process, e.g. switching motors, sensors and actuators. Because of this, the high efficiency of the SITOP PSU100C across the entire load range permits energy savings of up to 28%. 3) 5 0 Commonly used power supply SITOP PSU100C 24 V/1.3 A 0.0 Industrial power supplies are not usually operated for 24 hours a day over the entire year. During nonproductive periods, and at weekends or holidays, individual loads or plant sections are increasingly switched to a type of "standby operation" to save energy. The SITOP PSU100C supports this with especially low no-load losses and thus with energy savings of up to 53%. Commonly used power supply SITOP PSU100C 24 V/1.3 A 0 With its high efficiency in operation under load and in standby, SITOP compact enables you to make energy savings of up to 35% in normal use, i.e. with a mix of load and standby operation, in comparison with commonly used power supplies 3).
