Flexible, reliable and safe in every environment

Flexible, reliable and safe in every environment

Both in 24/7 production facilities and applications with the highest safety requirements as well, as in the field of simple applications in serial machine construction, three decisive factors are particularly important in terms of cost-effectiveness: plant availability, maintenance costs and energy requirements. As a result, the demands made on uninterruptible power supplies are high. When choosing the right uninterruptible power supply, particular attention should therefore be paid to longevity, energy efficiency and reliability. While space-saving solutions are increasingly becoming the obvious choice due to the ever-increasing range of functions involved, the ability to communicate also plays an increasingly decisive role. Our switched-mode power supplies meet all of these product requirements while ensuring that your business remains both efficient and competitive.

Our uninterruptible power supplies product range

UPS System

The modular design allows the complete load to be split into non-safe and safe load circuits, often enabling a smaller UPS to be designed.

  • Different status relays for status monitoring
  • Long battery service life thanks to integral deep discharge protection and temperature-compensated battery charging
  • Especially space-saving due to a small width of 66 mm

Buffer Module

Our buffer module is a practical way of being well-equipped for difficult network situations, especially in rural areas.

  • Bridge 20 A for 260 ms with ease
  • Increase the current or buffer time by simply connecting two modules in parallel
  • State of the buffers displayed visually by LED and signalled electrically with a relay and a transistor output

Battery module

Our DURAeco series is a flexible and user-friendly battery solution in a cost-effective design.

  • Sealed and maintenance-free lead-fleece batteries
  • Temperature sensor provides optimum battery charging and battery life
  • Safe and quick fitting thanks to plug-in connections


Optimal support for your power supply. Here you will find all the data on the operation of our power supply systems. In addition, further information on the software updates is stored.

Further product families and accessories

Optimise your power supply with accessories from the Weidmüller product range. For example, by creating a redundant power supply using our modules, you can protect your switched-mode power supplies from failure of the 24 VDC control voltage. We have the right product for every requirement and can also help you identify the right solution for your needs.

Redundancy and diode modules

The benefits of establishing a redundant supply are twofold: neither the failure of a switched-mode power supply nor that of an individual phase will cause the 24 V DC control voltage to fail. Each redundant branch is capable of supplying the full output load separately.
