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.In the first delivery stage, Siemens supplies two units for the output voltage 24 VDC, 0.6A/15W and 1.3A/30W, as well as a unit for 12 VDC with 2.0A/24W.
Further units with output voltages of up to 100W will follow. The Sitop PSU100C switched-mode power supplies have a wide-range input for single-phase AC networks between 85–264V and for DC networks between 100–300V. One of the main characteristics of the Sitop PSU100C power supplies is the high energy efficiency. For example, energy losses during no-load operation – such as in standby mode – are extremely low at around 0.5W. The constantly high efficiency across the entire load range, including partial-load operation, also saves energy. The new units are ideal for operating temperatures between -20°C and +70°C and feature an adjustable output voltage and a user-friendly connection system using plug-in terminals.
The space-saving, slim-line design of the unit requires only a minimum of mounting space on the DIN rail. Backed up by comprehensive international certification packages such as ATEX and Germanischer Lloyd, the units are suitable for decentralized applications in industry, infrastructure and building technology all over the world – ranging from mechanical engineering (series and special machines) through heating & air-conditioning systems, conveyor and safety technology and transportation systems to regenerative energies and agriculture.
