3-phase, 48 V DC Siemens

Обзор



The 3-phase SITOP modular are technology power supplies for sophisticated solutions and offer maximum functionality for use in complex plants and machines. The wide-range input allows a connection to almost any electrical power system worldwide and ensures a high degree of safety even if there are large voltage fluctuations. The power boost provides up to three times the rated current for brief periods. In case of overload, you can choose between constant current with automatic restart or latching shutdown. The high degree of efficiency keeps energy consumption and heating in the control cabinet low, and the compact metal housing also saves space.

Main product highlights

  • 48 V DC / 10 A and 20 A
  • 3-phase wide-range input
  • Extremely slim design – no lateral installation clearances required
  • Power Boost with 3 times the rated current (for 25 ms) for tripping protective devices
  • Extra power with 1.5 times the rated current (5 s/min) for brief functional overload
  • Selectable short-circuit response between constant current and restart
  • Optional symmetrical load distribution for parallel operation
  • Operating status on 3 LEDs
  • Extremely high efficiency to 94 %
  • Wide temperature range from -25 to +70 °C
  • Comprehensive certifications, such as cULus, ATEX and GL
