Neumüller's wide range of AC/DC and DC/DC power supplies offers the optimum solution for every requirement. The highest reliability and long service life of our power supplies ensure maximum system availability even under adverse environmental and grid conditions. Our power supplies are electrically and mechanically robust and thus ensure a continuously stable DC voltage supply under various load conditions. The majority of our highly efficient power supplies have a wide-range voltage input and are therefore protected against interference from the mains and on the DC side. High voltage peaks and surge current loads do not pose a problem for the power supplies. The mechanical resilience of the power supplies is ensured by shock and vibration resistance. The high power density and high efficiency of our power supplies ensure even better economic efficiency. A high degree of efficiency and a particularly small design can be achieved by sophisticated circuit technology and high-quality components. High efficiency results in only a very low thermal load on the components and improves the service life and reliability of the overall system. The space saving as well as the improved efficiency lead to lower overall costs. In addition to the standard range, we also offer customer-specific solutions for very individual requirements in relatively small quantities!
