The powerful standard power supply for 1- and 3-phase networks
Compact. Overload-capable. Powerful. SITOP smart.
A high standard for optimal power ...
With SITOP smart, even loads with high power demand can be connected without difficulty, thanks to its overload capability of 150 percent “Extra Power.” The 24 V power supplies can continuously manage 120 percent of the rated power.
Thanks to their slim design and seamless installation next to laterally mounting devices, the power supplies take up hardly any space on the DIN rail. The high degree of efficiency ensures low energy consumption as well as minimal heat generation and heat loss in the control cabinet. The flexible input voltage range allows problem-free connection to 1- and 3-phase networks around the world.
Comprehensive certifications also facilitate universal usage, for example in hazardous areas. To further increase the availability, the reliable power supply units SITOP smart can be combined with DC UPS, redundancy and selectivity modules.
