Power Supplies for Home and Building Automation

Smart homes and buildings require reliable power supplies for sensors, actuators, communication nodes, and controllers. To meet this demand, RECOM provides a wide range of AC/DC products available in encapsulated, open frame, and DIN rail formats. These power solutions are cost-effective, dependable, and rated from 2W to 300W peak. They feature flexible input voltage ranges and meet all necessary approvals for global home and building automation applications.

Modern smart homes integrate a variety of features, including connected multimedia, lighting control, security systems, HVAC management, and occupancy simulation. Typically, all devices are wirelessly connected and can be securely controlled remotely via smartphone apps, offering both convenience and energy savings. This equipment requires AC/DC power supplies ranging from a few watts for wall-mounted temperature controls to hundreds of watts for remotely operated garage doors. While some simple nodes may use batteries, most smart home systems operate directly on AC mains. RECOM is a preferred provider of these embedded power supplies.

Commercial and industrial buildings are increasingly adopting automation to achieve energy savings, enhanced security, convenience, and improved operational efficiency. Similar to smart home applications, these systems require AC/DC converters to support connected equipment, but they also need to withstand more challenging, harsh, and less controlled environments.

These automation power systems often operate up to 277VAC, requiring components that are both cost-effective and reliable, with long service lifetimes. RECOM's AC/DC power supplies are ideal for these applications, available in encapsulated, open-frame, and DIN rail formats. They deliver consistent performance across a wide temperature range, with many models rated for Over Voltage Category III (OVC III) to ensure enhanced immunity to mains transients.
