Power supply 55W 27.6V, 5V, 26.5V ADD-55B

Buffered power supply with UPS function – reliable power supply for security and automation systems

This buffered power supply from Mean Well's ADD series is the ideal solution for systems requiring continuous power, such as alarm systems, CCTV monitoring, access control or building automation. The device not only stabilizes the output voltage but also, in conjunction with a battery, functions as an Uninterruptible Power Supply (UPS), ensuring uninterrupted operation in the event of a mains power failure.

Versatility and protection

The ADD-55B power supply is designed to operate within a wide range of input voltages (88-264VAC, 124-370VDC) and offers several outputs with different voltages (5V, 26.5V, 27.6V), making it extremely versatile. Built-in short-circuit, overload and overvoltage protection protects both the power supply itself and the devices connected to it. Additionally, the deep discharge protection function for the battery extends its lifespan and ensures system reliability.

Ease of use and installation

The device is characterized by high efficiency (74%) and effective free air convection cooling. The ability to adjust the output voltage within the range of +/- 10% allows for precise parameter adjustment to the needs of a specific application. Compact dimensions (159x97x38mm) and the possibility of mounting on a DIN rail (using adapters) facilitate installation even in limited space. LED signaling informs about the operating mode of the device and the status of the battery.
