Siemens Sitop PSU8400 and Sitop SEL1600 power supply system
The Sitop PSU8400 3-phase power supplies and Sitop SEL1600 selectivity modules can be conveniently parameterised and diagnosed via integrated displays or IO-Link. This enables high transparency and enhances the reliability of the 24 V supply and its individual load branches.
According to Siemens, the compact 24 V/20 A and 40 A power supplies have a degree of efficiency of 96% and adjustable overload behaviour. The selectivity system consists of a basic module with four 10 A outputs each and can be expanded to up to 40 outputs via expansion modules. The modules of the Sitop PSU8400 and Sitop SEL1600 can be easily connected via prefabricated 24 V brackets and data cable; however, they can also be combined independently of each other with other power supplies or selectivity modules.
