SITOP PSU300S 40A Regulated power supply Input: 3 AC 400-500 V Output: DC 24 V/40 A *EX approval no longer available* The 3-phase SITOP smart are the universal and powerful standard power supplies for machine and plant engineering. Despite their compact design, they offer excellent overload behavior: Thanks to extra power of 150%, consumers with high power consumption can be switched on without any problems and the permanent overload capacity of 120% offers power reserves for expansions. The high efficiency ensures low energy consumption and low heat generation in the control cabinet. To further increase the 24 V availability, the SITOP smart power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules. No matter what industry, no matter what requirements - Siemens offers reliable and efficient power supplies for every system.
