Power Supply 4.0 – More Power for Your Control Cabinet

Fast, flexible, as cost-effective as possible – in the face of increasing cost pressure, scarce resources and tight delivery times. The demands on the control cabinet industry are steadily increasing. Production processes are undergoing more and more digitization and automation to reduce costs and save time, with power supplies playing a decisive role.

But what does a modern power supply look like? And what must it be able to do? With the WAGO Pro 2 Power Supply, WAGO introduces future-proof devices to power your application: Choose the power of the possible!

Save Time with Modular Circuit Diagrams

A modern power supply must basically do one thing: Convert alternating current into a safely electrically isolated direct current. It is simultaneously necessary to save time and money – but how? According to a 2017 study by EPLAN and the Institute for Control Engineering of Machine Tools and Manufacturing Units at the University of Stuttgart, planning and creating the circuit diagram account for over 50 % of the design time. There is significant potential here for savings. This study on Control Cabinet Manufacturing 4.0 shows that switching from project-specific or order-oriented circuit diagrams to modular circuit diagrams can trim the engineering process times by up to 45 %. There is significant potential for optimization like this in control cabinet manufacturing and in the power supply, since many steps are still performed today without automation. 92 % of the study participants surveyed still rely on two-dimensional engineering. But why? One industry that is facing particular challenges in this regard is the automotive industry.

The Automotive Industry: Increasing Demands on Power Supplies

If an auto manufacturing system is idle for even a few minutes, it can quickly cost several thousand euros and mean fewer vehicles produced. This is made all the more frustrating if it’s caused by a failed power supply whose original price was only a fraction of these costs. To avoid this, choosing a reliable power supply is imperative. “Availability plays an important role for automobile manufacturers above all else. An important selection criterion for the power supply is its theoretical life expectancy,” says Manfred Grabowski, Automotive Key Account Manager at WAGO. It’s worth closely inspecting the datasheets when selecting the power supplies: Comparable devices may differ significantly when you look a little closer. A long life expectancy is usually also associated with low heat generation and low power loss. The example of power loss makes it clear that proper selection and dimensioning of power supplies can also reduce energy costs.
