The electrification of products and entire industries has been in high demand, and not just since the new geopolitical situations in 2022. The electrification of mobility is progressing in all economic sectors, and REO components daily prove their resilience and reliability. Thanks to the high scalability of power classes, mobility solutions can be electrified, from small autonomous robots to buses and even container ships. The advantages of electrified drives are obvious. Electric drives exhibit very good efficiency compared to conventional drive types like internal combustion engines. At the same time, e-drives have a significantly lower weight-to-power ratio and produce no local emissions. However, for an electrified drive system to operate safely and reliably, special components are required. For example, REO braking Resistors protect the machine from overvoltage in the DC link. For your applications (e.g., wind power technology, railway technology, automotive technology), they guarantee high operational safety and are overload-proof under short-term load. The charging resistor, on the other hand, is a current-limiting resistor for charging and discharging capacitors and limits, for example, the inrush current flowing into the DC link capacitor. For this purpose, the device must be designed for high single-pulse energy and rated voltage. For particularly effective cooling in the most adverse conditions, REO offers a wide range of liquid-cooled components. Liquid-cooled Resistors, such as REO’s REOHM D 330, are significantly smaller than conventional air-cooled Resistors and are available in power ratings up to 60 kW. Efficient cooling is achieved by means of cooling channels integrated into the heat sink, which enable cooling below ambient temperature and create a safety-relevant spatial separation of the current-carrying and liquid-carrying lines. Further advantages include high power density, and efficient and low-noise operation.

REO products are characterized by a long service life and low maintenance requirements. This not only has financial advantages, but also saves resources that are needed for new products or spare parts. With our products, you can therefore contribute to minimizing the global waste of resources. Become part of REO’s consistent path to greater sustainability. We have set the course for a sustainable future and stand behind our ambitious goals. Our claim is based on the holistic strategy of reducing emissions and consumption in all production and company areas.
