Reliable Power for Critical Systems

Security cameras, access control panels, and alarm systems cannot afford power drops or voltage spikes. The AD-55 series provides a steady 55W output with precise voltage regulation.

Easy to Install and Maintain

Installers appreciate the straightforward setup. The AD-55 units feature a slim, lightweight housing that fits neatly into standard enclosures or mounts directly to walls and DIN rails. Clear terminal markings, secure screw connections, and low operating noise make field work faster and safer. High efficiency means less heat buildup, which extends the life of both the power supply and your connected devices.

Two Smart Voltage Options for Any Job

This series covers the most common requirements in the field. The 27.6V 2A model (26.5V 0.16A) is ideal for longer cable runs and high-demand sensors.
