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

Extremely compact power supply for 1-phase networks

The new SITOP PSU8200 1-phase technological power supplies of the SITOP modular series require very little space on the standard mounting rail thanks to their very compact design. With an installation depth of just 55 mm, the 10 A version is the slimmest power supply unit in its performance class. The high efficiency of up to 94% results in very low energy consumption. Energy savings can also be made with the "Remote ON/ OFF" function, which can be used to turn off the power supply unit remotely. If more power is required, however, as for switch-on surges, the "Extra Power" feature can provide 1.5 times the rated current for brief overloads.

One power supply for all networks worldwide

The 5 A and 10 A power supplies of the SITOP modular series have been innovated. They now have a signaling contact for easy plant integration and higher efficiency. It has been increased to 91% for the 10 A device which resulted in a narrower enclosure width of 70 mm reduced from 90 mm. Like their predecessors, PSU200M are characterized by their unique ultra-wide range input which enables worldwide operation in 1-phase networks with 120 to 230 V as well as operation on two phases of a three-phase network with 230 to 500 V rated voltage.
