Switched-mode buffer power supply for built-in mounting PSB 13.8V/2A PSB-12V2A

Reliable buffer power supply for security systems and more

The PSB 13.8V/2A buffer power supply is a solid solution for ensuring uninterrupted power supply in alarm systems, video surveillance, access control and other devices requiring a stable 12V DC voltage. The device is characterized by high efficiency and reliability, which translates into long-term and trouble-free operation. The housing design allows for discreet integration with the installation, and the possibility of mounting on a DIN rail (using an optional bracket) facilitates installation and servicing.

Functionality and safety in one

The PSB-12V2A power supply not only provides a stable output voltage of 13.8V DC with a current of 2A, but also functions as a battery charger – the charging current is 0.5A. Thanks to this, in the event of a mains power failure, the connected battery automatically takes over the power supply, guaranteeing uninterrupted operation of the connected devices. Built-in protections – SCP (short-circuit), OLP (overload), OVP (overvoltage) and UVP (deep discharge protection) – protect both the power supply itself and the devices connected to it from damage. Additionally, reverse battery connection protection increases the safety of the installation.

User comfort and easy installation

The power supply is equipped with LEDs indicating the operating status – the presence of AC voltage, DC voltage at the output and battery charging process. This allows for quick diagnostics and identification of any problems. The set includes battery cables with angled lugs, which facilitates connection. The dimensions of the device (110 x 78 x 36 mm) allow for mounting in a limited space. Protection class I requires the use of a protective conductor during installation. The power supply has a CE declaration and is covered by a two-year manufacturer's warranty – Pulsar K. Bogusz Sp. J.
