Power Supplies for Home and Building Automation

Modern smart homes and automated commercial buildings rely on always-on power supplies that draw a low standby current to operate complex networks of sensors, actuators, smart switches, HVAC controls, and security nodes. RECOM provides a versatile portfolio of AC/DC power supplies engineered for extreme space efficiency, minimal idle power consumption, and global regulatory compliance across residential and industrial building management systems (BMS).

Available in miniature encapsulated, open-frame, wired, and DIN-rail mounting formats, these power modules deliver output power ratings from 2W up to 1.5kW peak. Featuring wide input voltage ranges (including 100VAC, 277VAC and 480VAC line-to-line options), Ecodesign Lot 6 compliant low-standby power, and compliance with household (IEC/EN 60335-1) and industrial (UL/IEC/EN 62368-1) safety standards, RECOM power supplies streamline circuit design and simplify global EMC certification.

Residential smart home devices—such as wall-mounted thermostats, flush-mount smart switches, smart lighting controls, and motorized blinds—demand ultra-compact AC/DC power modules that can fit inside constrained electrical junction boxes (in-wall boxes) or tight plastic enclosures.

Key Capabilities:

• Ultra-Compact Form Factors: Miniature PCB-mount, flying-lead, and screw-terminal designs engineered to fit behind standard wall plates and inside junction boxes.
• Low Standby Power & High Efficiency: Designed for zero-loss standby compliance, ensuring connected IoT nodes draw minimal power when idle.
• Household, Industrial & Building Safety Compliance: Certified to IEC/EN 60335-1 (household appliances), IEC/EN 61558 (power transformers), UL/IEC/EN 62368-1 and NEC Class 2 / LPS (Limited Power Source) limits for safe, unmonitored home operation.

Commercial facility automation, energy management, and smart office systems operate in harsher, less controlled electrical environments than residential homes. These applications require ruggedized AC/DC converters, DIN-rail units, and chassis-mount supplies capable of withstanding heavy mains transients and elevated line voltages (up to 277VAC nominal).

Key Capabilities:

• Overvoltage Category III (OVC III) Rated: Many modules are tested and certified to OVC III levels, allowing direct installation into primary distribution panels and building mains without external surge suppression components.
• Flexible Mounting Formats: Offers PCB-mount, wired, push-in terminal, and slim DIN-rail configurations for rapid installation in HVAC control cabinets, elevator panels, and lighting distribution boards.
• Extended Temperature Performance: Reliable operation across ambient temperature ranges from -40°C up to +80°C, ensuring continuous performance in unconditioned plant rooms and outdoor control boxes.
