Siemens Industry Automation Division has expanded its power supply offering with the Sitop lite range. The Sitop PSU100L power supplies are designed for single-phase connection and offer all important functionalities at an attractive price/performance ratio. They deliver controlled 24V and are available in three performance classes with rated output currents of 2.5, 5, and 10A. Power supplies of the same type can be connected in parallel to increase the performance. The power supplies are designed for single-phase connection and offer all important functionalities at an attractive price/performance ratio. The new product range has been primarily designed for use in machines and plants whose automation components have to be reliably supplied with 24V but only have basic demands with regard to the scope of functions provided by the power supply. Like all Sitop power supplies, these products are also characterised by particularly high reliability and fulfill all the requirements for universal use. For example, the wide-range input with manual switchover supports connection to all industrial supply systems. The small widths of 32.5, 50, and 70mm mean that the primary switched-mode regulators occupy little space on the DIN rail. The fan-free power supplies can be operated at ambient temperatures from 0 to 60°C and have an efficiency of up to 89%.
