Modern cooking appliance manufacturers continue to strive to design more powerful, efficient & innovative products. Consumers are increasingly demanding healthy, high quality food and, at the same time, faster cooking processes.

In this case study, Holger Urban, Product Marketing Manager at EMC & power electronics specialist, Schaffner explains how German start-up, Scraegg used its EMC filters in its innovative scrambled egg appliance to ensure optimised usage alongside other appliances.

In modern commercial and larger home kitchens, a multitude of different appliances are likely to be used side by side. This means that regard for electromagnetic compatibility (EMC) has an essential role in the design of all cooking devices. To avoid unintended disturbances and product malfunctions, each of the appliances must comply completely with the mandated EMC value limits. This is where EMC filters enter the equation.

The function of EMC filters

Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment. Several electronic devices running in parallel may cause unwanted electromagnetic interference effects or disturbances and may even influence other devices’ functionality. The is particularly true where products feature microprocessor control or programming. To counteract such effects, protection requirements regulated by law must be satisfied. The deployment of EMC filters defends the electronic environment against such dysfunctionalities. As the international market leader in EMC filters, Schaffner continuously develops new flexible, efficient and powerful solutions for diverse applications.

Schaffner’s EMC filters are routinely used in many different domestic appliances, be it coffee machines, food processors or a new appliance for cooking scrambled eggs to take away – as recently developed by the innovative Scrægg start-up in Wiesloch and Heidelberg (southwestern Germany). With their unusual and very fast method of preparing a scrambled egg, Scrægg is clearly on the road to success. Just one year after the foundation of the start-up, the Scrægg device has sold very well and the entrepreneurs have experienced such strong growth that they were able to expand their production capacity, their factory site and their team. The idea behind the flagship product is as simple as it is ingenious: a steam nozzle prepares a delicious scrambled egg in just 15 seconds without any fat. A global food industry sensation!

Efficient and functional thanks to Schaffner’s Power Entry Module

What is the EMC secret behind the innovative egg scrambling system? Scrægg installs Power Entry Module filters (PEM) of the Schaffner FN9280/90 series. Even just during the product development phase the deployment of Schaffner’s IEC inlet filters greatly reduced both design time and effort. With measurements made with the Schaffner Power Entry Module filter fitted, fast and functional solutions could be worked out directly to any noise problem.

The very space-saving design of the installed Power Entry Module combines a 2-pole isolating rocker switch and dual fuse holder in one unit and with a height of only 46 mm, it is the ideal solution for the innovative Scrægg system. Additionally, the Power Entry Module filters provide maximal flexibility with various mounting possibilities.
