SITOP smart

The high-performance standard power supply for 1-phase and 3-phase networks

SITOP smart is the high-performance standard power supply for automated machines and systems with 24 V or 12 V electronics. Despite its compactness, it offers outstanding overload characteristics. Its capacity of 1.5 times the rated current for 5 s/min also enables trouble-free connection of consumers that demand high power. And with the permanent load capacity of 120% nominal output, these compact power supply units are among the most reliable of their kind

To further increase the availability, the SITOP smart power supply units can be combined with DC UPS, redundancy and selectivity modules.

The advantages at a glance

  • Small footprint thanks to compact design, no clearances required at the sides
