About KALEJA
KALEJA GmbH, based in Alfdorf, develops and produces motor controllers, drive regulators, semiconductor relays (SSR) and interface technology for DC, BLDC and EC motors in industrial applications. All hardware and software development of the power electronics is carried out in-house using modern CAD systems; in addition, custom motor controllers and tailor-made drive systems are realized. The portfolio includes motor controllers, electronic load relays, fan controllers, mounting modules, EMC filters and interference suppression components, DC/DC converters, wiring interfaces as well as brake choppers and surge limiters for DC networks, all designed for mounting on DIN rails. The company supports customers from rapid sample building and production-ready prototypes through to series production with stock keeping, global logistics and obsolescence management. The products are used in mechanical engineering, automation technology, building automation, intralogistics, rehabilitation technology and other industries; customers exist in more than 35 countries worldwide.
