PoE buffer power supply for PCB mounting 52V/1.15A/1xBAT PWB-52V1A

Buffered PoE Power Supply for Surveillance and Network Systems

The PWB-52V1A power supply is a switch-mode device dedicated to powering PoE systems, switches, IP cameras and other devices requiring 52V DC. Its design allows for mounting in an enclosure, making it an ideal solution for installers of surveillance and computer network systems. It provides uninterrupted power to connected devices, protecting them from the effects of power outages.

Construction and Functionality

The power supply is designed for reliability and ease of use. It is equipped with a START function, allowing manual activation of power from the battery - useful for example during battery replacement or in the event of a mains power failure. Built-in protections protect both the power supply itself and the devices connected to it against short circuits (SCP), overloads (OLP), overvoltages and incorrect battery connection. Battery charging and maintenance control ensures its longer life and optimal system performance. LED optical signaling informs about the power supply's operating status and battery charging.

Parameters and Applications

The PWB-52V1A power supply offers up to 67W of power at an output voltage of 52V DC and a maximum output current of 1.15A. Efficiency at 87% translates to minimal energy losses and stable device operation. The ability to connect batteries with a capacity of 7Ah or 17Ah allows you to adjust the hold-up time to individual needs. The power supply is compatible with lead-acid batteries, ensuring wide availability and ease of replacement. Thanks to its compact dimensions (200 x 48 x 120 mm) it is easy to mount in a limited space. Designed to operate at temperatures from -10°C to +40°C, which guarantees its reliability in various environmental conditions.
