Description
Manufacturer Part Number: AD-155B
The AD-155B is an enclosed AC-to-DC switching power supply designed to provide regulated 27.6V DC power and battery charging for security systems, access control equipment, telecommunications devices, and other critical electronic applications. It accepts a universal input voltage range, making it suitable for installations using different AC mains standards. Its integrated battery charging control allows an external battery to be connected to provide backup power when the mains supply fails.
The AD-155B uses fanless, free-air convection cooling for quiet operation and includes protection against short circuits, overloads, overvoltage, low battery voltage, and reverse battery polarity. Its secondary 27.1V output provides a charging connection, while the main output is adjustable between 24V and 29V DC. This combination makes it useful for systems that need both a regulated DC supply and battery-backed operation without a separate standalone UPS.
