SITOP PSU300S 24 V/5 A Stabilized power supply input: 3 AC 400-500 V output: 24 V DC/5 A The SITOP smart 3-phase power supplies are the universal high-performance standard power supplies for machine and plant construction. Despite their compact design, they offer excellent overload response: Thanks to 150% extra power, loads with high power consumption can be connected without any problems and the permanent overload capacity of 120% offers power reserves in case of expansions. The high degree of efficiency ensures low energy consumption and minimal heat generation inside the control cabinet. To further increase 24 V availability, the SITOP smart power supplies can be combined with buffer, DC-UPS, redundancy and selectivity modules. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.
