SITOP modular

The technological power supply for demanding solutions

The one-phase, two-phase and three-phase SITOP modular are the technological power supplies for demanding solutions. They 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. They offer an excellent overload behavior: The Power Boost supplies up to three times the rated current for a short time, and with the extra power of 150%, consumers with high power consumption can be connected without problems. Moreover, you can choose between constant current or automatic restart in case of overload. The very high efficiency keeps the energy consumption and heat generation in the control cabinet to a minimum, and the compact metal enclosure requires less space.

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

The benefits at a glance

  • 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, operational overload

  • Optional short-circuit behavior between constant current and restart

  • Optional symmetrical load distribution for parallel operation

  • Extremely high efficiency up to 94%

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

  • Comprehensive certifications, such as cULus, ATEX or GL

New: SITOP PSU8200, 3-phase 24 V/40 A

For very high requirements on reliability, functionality and universal use

The innovated SITOP power supply PSU8200, 3-phase 24 V/40 A, meets all requirements on a technology power supply for demanding solutions. The increased degree of efficiency ensures better energy performance. The reduced width and optimum heat dissipation enable a compact structure with arrangement of components directly in a line. The possibility of switching the power supply on and off using remote access increases the range of potential applications. Reliability of the new power supply unit is guaranteed by integrated functions which ensure stability of the input circuit against mains reactions and overvoltage. The option of permanent 2-phase operation makes for improved plant availability.
