About SE-Elektronic – Empowering Industries with Smart Automation

Pioneering German-made building automation solutions since 1983 — delivering innovation, reliability, and custom-engineered control systems worldwide.

History Until Today

Founded in 1983, SE-Elektronic GmbH has evolved from a small control systems manufacturer into a leading innovator in building automation and energy management. From the early P-KRC controllers of the 1980s to today’s advanced BACnet/IP and Webserver-based DDC systems, the company has consistently pioneered high-performance, German-engineered solutions.

Over the decades, SE-Elektronic has introduced numerous industry-firsts — including intelligent graphical operator interfaces, customized control panels, and energy-efficient remote access solutions. Each development has been tailored to meet the growing demand for scalable, user-friendly building management technologies.

Key milestones include:

1983–1992: Launch of early DDC controllers and HMI displays
1998–2005: Expansion into modular systems and customizable automation platforms
2009–Today: Introduction of BACnet/IP communication, HTML5 web visualisation, and integrated energy dashboards
2013: Seamless integration with EnOcean, a wireless energy harvesting standard

Today, SE-Elektronic remains at the forefront of building automation — offering a full suite of sensors, actuators, software, and custom-engineered solutions for projects across commercial, industrial, and public sectors.
