China, April 15, 2026 — Yudian Automation Technology Co., Ltd., a global leader in intelligent temperature controller manufacturing, announced that its AI-85X series temperature controllers have successfully obtained TÜV SÜD functional safety certification, making Yudian the first temperature controller brand in China to receive this authoritative certification.
TÜV SÜD functional safety certification is one of the most rigorous international safety standards, recognized across safety-critical industries including semiconductors, industrial automation, and renewable energy. Achieving this certification signals that a product meets the highest benchmarks for reliability and risk control in demanding manufacturing environments.
The certification was completed over 13 months through a collaborative effort between Yudian’s technical team and TÜV SÜD’s China-Germany team. The process covered a comprehensive review of product design, hardware testing, software verification, production control, and documentation systems. The AI-85X series is developed for high-end manufacturing scenarios such as semiconductors, photovoltaics, and renewable energy. Equipped with Yudian’s self-developed APID intelligent regulation algorithm, it delivers precise temperature control with no overshoot or undershoot, achieving a highest temperature control accuracy of 0.002°C in precision manufacturing applications.
