Hirschau, April 2025. DC voltage supply is one of the key ingredients in automation scenarios. First of all, it is safe and reliable. Second, it is energy-efficient which helps lower costs. This first and foremost applies to expensive small equipment that require affordable power supplies. Weidmüller’s PRObas series comprising twelve highly efficient versions is now available on the Conrad Sourcing Platform. Which is something greatly appreciated by Dr Christina Dülme, managing director at Weidmüller, who looks after customers based in Germany, Austria and Switzerland: “We really like how quickly new products are listed on conrad.de, and the customer-specific marketing they do. Also, the interfaces that allow you to integrate Conrad’s e-catalogue into your own ERP systems really go down well with our shared business customers.”  

High Coefficient of Performance Brings Down Energy Use

DInnovative electric components, circuitry and mechanical parts used in Weidmüller’s PRObas 1-phase power supply units result in efficiency ratings of up to 95 percent and very low idle state energy loss. This brings down running costs right away. Moreover, less energy use constitutes a valuable contribution to increase sustainability of equipment use across the industries.

Indiviualised, Compact and Robust

PRObas power supplies are fit for any purpose: there are twelve versions that cover DC voltage ratings of 5, 12, 24 and 48 V, respectively, allow a wide range of inputs and come with a 1-million-hour MTBF which makes the products suitable for a variety of scenarios. Moreover, their small size ranging between 23 and 59 mm means they don’t take up much space. In terms of installation, they can be latched on to DIN rail, or fitted to panel sides. The products are designed to withstand temperatures from -25 to +70 °C which makes them an ideal choice for harsh climates.

Easy Integration and Worldwide Compliance

PRObas series products are compatible with all Weidmüller fuses , DC UPS units and diodes, and can therefore be used in power management systems, providing the versatility you need when setting up complex energy supply systems. Extensive protection mechanisms and globally recognised certification ensure safety (even in challenging environments), easy integration and worldwide usability.
