SITOP smart

The powerful standard power supply for 1- and 3-phase networks

SITOP smart is the optimal power supply for many 24-V and 12-V applications, featuring compact design, powerful performance, and low price. Despite its compact size, it offers outstanding overload characteristics thanks to the extra power feature that provides 1.5 times the rated current for five seconds: Even large loads can be easily switched on. And with a rated capacity of 120 percent, these slim power supplies are among the most reliable of their kind.

Highlights The 1-phase and 3-phase SITOP smart are the universal and powerful standard power supplies for machinery and plant engineering with 24 V or 12 V electronics.

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.
