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 48 V/10 A

For very high requirements in limited spaces

SITOP PSU8200 enlarges our portfolio in the product line SITOP modular for 3-phase networks impressively. The 10 ampere technology power supply may be installed also in limited spaces because of its narrow design of just 70 mm. The low energy consumption and the minimal heat generation inside the control cabinet are based on a very high efficiency of up to 94 percent. Even in the event of a short-time overload the high system availability is ensured by supplying up to 3 times the rated current for 25 ms or 1.5 times the rated current for 5 s/min. The power supply is enabled for worldwide use by the wide-range 3-phase input (AC 320 - 575 V AC) and extensive certifications (including IECex). Thanks to the comprehensive functionality this new power supply may be used optimally in the process industry as well as in the discrete industry.
