About Schäfer Elektronik

Schäfer Elektronik GmbH, headquartered in Achern (southern Germany), develops and manufactures industrial power supplies and power electronics: AC/DC and DC/DC converters, DC/AC inverters, AC/AC frequency converters, battery chargers and power supply systems from 100 W to 100 kW (modular up into the megawatt range), thyristor-controlled chargers from 500 W to 500 kW, and active harmonic filters for mains compensation. In addition, the company offers stationary and mobile charging infrastructure for e-mobility as well as the patented personalized machine unlocking system (PMF) for machine safety. The solutions are often designed for safety-critical applications on land, at sea and underwater, and are customized or newly developed to customer requirements. Customers include the power plant and defense industries, rail, oil and gas, marine/deep-sea, automation and the semiconductor industry, as well as data centers. With around 200 employees worldwide, a production facility in Ireland and sales offices in the USA and the UAE, the company serves customers globally.
