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

  • "Extra power" with 1.5 times the rated current for 5 s/min for transient overloads

  • 120% of the rated capacity can be used durably up to 45 °C ambient temperature (24 V models)

  • Signaling contact for "Output voltage OK" for easy integration into the system monitoring

  • Low energy consumption and minimal heat generation inside the control cabinet due to high
    efficiency

  • SITOP PSU100S: Automatic range switching 120/230 VAC

  • SITOP PSU300S: Wide -range input 3AC 400 – 500 V

  • Adjustable output voltage to compensate for voltage drops

  • Wide temperature range from -25 to +70 °C

  • Comprehensive certifications, such as cULus, ATEX, IEC or GL for all standard applications worldwide


New: SITOP PSU300S 24 V/5 A and 10 A


The standard product line SITOP smart has been extended with a 5 A power supply and a 10 A version for smaller power demands on 3-phase systems. The new SITOP PSU300S with a 5 A rated output current and a width of only 50 mm can be mounted on a DIN rail. The width of the 10 A variant has been reduced by 20 mm to 70 mm.

Their high efficiency of up to 91% for both power supplies generate only a small amount of heat in the control cabinet. The devices have a 3-phase input range of 340 VAC to 550 VAC, that reliably ensures an output of 24 volts, even if there are large fluctuations in the supply voltage. The extra power of 1.5 times the rated voltage for five seconds makes it possible to carry loads with high power requirements.

The international certifications such as ATEX, IECEx, and GL as well as an ambient temperature range from -25 to 70 °C mean they can be used in diverse industries around the world.
