Mean Well - AD-155 Series

The Mean Well AD-155 series is built for reliable power delivery in demanding electrical and security setups. These compact power supplies are designed to keep your systems running smoothly, whether you are wiring CCTV cameras, access control panels, or emergency lighting. With a steady 155W output, they handle both normal operation and backup power needs without breaking a sweat.

Reliable Power for Critical Systems

Installers know that downtime is not an option. The AD-155 series delivers stable voltage and current to keep your equipment online. It features built-in protections against short circuits, overloads, and overheating. This means you can mount it in tight control cabinets or outdoor enclosures with confidence, knowing it will protect your investment and reduce service calls.

Two Ready-to-Use Voltage Options

This series comes in two straightforward models to match your project needs. The first model outputs 27.6V at 5.5A, with a backup boost to 27.1V at 0.5A, perfect for standard 24V DC systems. The second model provides 54V at 2.7A, stepping down to 53.5V at 0.5A for higher voltage applications like long cable runs or PoE cameras. Both models plug directly into your existing wiring without extra converters.

Easy Installation and Maintenance

Designed with the installer in mind, the AD-155 units feature clear terminal markings and a slim DIN-rail or wall-mount design. You can wire them quickly using standard tools, and the compact footprint saves space in crowded panels. The sealed housing resists dust and moisture, making it suitable for basements, utility rooms, or covered outdoor locations. Routine checks are simple, and the robust build means fewer replacements over time.

Built to Last in Real-World Conditions

Mean Well has a strong reputation for quality, and the AD-155 series continues that tradition. These power supplies are tested to handle voltage spikes and temperature swings common in commercial and industrial sites. By choosing this series, you get a dependable backup power solution that keeps your electrical and plumbing control systems, security networks, and monitoring gear running exactly when you need them.
