Information about the MEAN WELL ADD-55A

The MEAN WELL ADD-55A is a highly specialized dual-output power supply engineered with an integrated UPS function to ensure maximum system availability. This unit provides a primary 13.8V rail and a secondary 5V rail, alongside a secondary battery charging circuit that automatically manages backup power during AC mains failure. This multi-rail configuration is particularly effective for security systems, access control, and industrial monitoring equipment where maintaining power to both logic circuits and peripheral hardware is vital for operational continuity and preventing system reboots.

Durability is at the core of the ADD-55A design, featuring a rugged metal chassis and a fanless architecture that relies on free air convection cooling to extend the product's lifespan. It incorporates advanced protection logic, such as battery low-cut protections to prevent deep discharge, and a hiccup mode for automatic recovery after fault conditions are cleared. With its universal AC input range and compliance with the latest global safety standards, this power supply delivers a reliable and maintenance-free energy solution for space-constrained industrial environments requiring high-performance battery backup capabilities.
