SIEMENS SITOP smart 1-phase, 24 V DC

SITOP smart 1-phase, 24 V DC Overview

The one-phase SITOP smart are the universal and powerful standard power supplies for machinery and plant engineering. Despite their compact design, they offer an excellent overload response: Thanks to a power boost of 150%, loads with high power consumption can be connected without any problems and the permanent overload capability of 120% offers power reserves in case of expansions. The high degree of efficiency results in low energy consumption and minimal heat generation inside the control cabinet.

To further increase 24 V availability, the SITOP smart power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules.

Main product highlights
  • 1-phase, 24 V DC/2.5 A, 5 A, 10 A and 20 A
  • Input voltage 120 V and 230 V AC with automatic range switching
  • Compact design – no lateral clearances required
  • Extra power with 1.5 times the rated current (5 s/min) for brief functional overload
  • Permanent overload capability with 1.2 times the rated current up to 45 °C ambient temperature
  • Adjustable output voltage for compensating voltage drops
  • Signaling contact for easy integration in the plant monitoring system
  • Wide temperature range from -25 or 0 to +70 °C
  • Comprehensive certifications, such as cULus, cCSAus, ATEX, IECEx and DN
