AS-Interface power supplies are specialized industrial power supply units designed for the AS-Interface (Actuator-Sensor Interface) system, a globally recognized automation networking standard. These power supplies are typically produced by leading industrial automation companies, such as Siemens (Germany), Bihl+Wiedemann (Germany), and Pepperl+Fuchs (Germany). They serve industries like manufacturing, process automation, and logistics by providing reliable power to sensors and actuators in harsh environments. Key products include ASi power supply units with integrated data decoupling, ensuring seamless communication and power distribution within the AS-Interface network. These devices are known for their robustness, safety features (e.g., short-circuit protection), and compliance with international standards like IEC 62026-2.
