Switch mode power supplies: universally applicable for all applications

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 placed on switch mode power supplies are high. When choosing the right 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 switch mode power supplies meet all of these product requirements while ensuring that your business remains both efficient and competitive.

Ideal for reliable impulse triggering of circuit breakers or as an additional energy source for powerful motor starts.

PROmax – "the powerhouse"

Power and durability – these are the qualities that differentiate our PROmax switched-mode power supplies from the competition. They can cope with continuous overloads of up to 20%. Even short-term peak loads of 300% occurring with high control cabinet temperatures will not affect these switched-mode power supplies. Offering high levels of scalability and full performance across a wide range of temperatures, they are particularly suitable for demanding requirements and the challenges of automation. Despite their outstanding performance, our products have a small overall width, ensuring that the power supplies will fit into almost any control cabinet. You can combine the products in our PROmax range with our diode and CAP modules or our uninterruptible DC UPS units to find an individual solution that meets your needs.

  • Safe operation with high power reserves up to 60°C and start-up at −40°C
  • Capable of handling continuous overload or transient peak loads with ease
  • Suitable for confined spaces thanks to their narrow width
  • International approvals (cULus, DNV, RMC/ACMA, TÜV)


High performance, compact design and a good price-performance ratio are the main characteristics of the new PRObas power supplies. The product family comprises 12 variants with 5, 12, 24 or 48 V DC output voltage and a wide-range input. All units have comprehensive safety functions and are internationally approved. Due to compatibility with our electronic fuses, DC UPS and diode modules, they are also suitable for setting up power management systems.

  • Compact design with flexible mounting (DIN rail or wall)
  • High efficiency up to 95%
  • Wide operating temperature range from −25 to +70°C (start-up at −40°C)
  • International approvals (cULus, NEC Class2 and cCSAus)

Other product families and accessories for switch mode power supplies

Optimize your power supply with accessories from the Weidmuller product range. For example, by creating a redundant power supply using our modules, you can protect your switch 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 for switched mode power supplies

The benefits of establishing a redundant supply are twofold: neither the failure of a switch 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.
