Mean Well - ADD-55

The Mean Well ADD-55 series is a compact, high-performance power supply line built for security, access control, and monitoring installations. Designed with installers in mind, this series delivers stable, reliable power to cameras, electric locks, sensors, and control panels. Whether you are wiring a small business or a large facility, the ADD-55 gives you the consistency and safety you need without the guesswork.

Simple Setup and Smart Mounting

These units are built for fast, hassle-free installation. The compact metal housing fits easily into tight panels, and the DIN-rail mounting option saves time on every job. You get plug-and-play wiring with clear terminal markings, so you can connect power and loads quickly. The low-noise design and efficient cooling keep the unit cool even during long runs, reducing the need for extra ventilation or heat management.

Flexible Voltage Options for Every Job

The ADD-55 series offers two focused models to match your system requirements. The first model delivers 55W with outputs of 27.6V, 5V, and 26.5V, making it ideal for high-voltage locks and auxiliary sensors. The second model provides 55W with 13.8V, 5V, and 13.4V outputs, perfectly suited for standard access control and CCTV setups. Both units combine multiple voltages in one compact box, which cuts down on wiring complexity and keeps your electrical panels clean and organized.
