Buffered switch-mode power supply for installation PSB 13.8V/15A PSB-12V15A

Buffered power supply for security and automation systems

The PSB-12V/15A switch-mode power supply is a reliable solution for uninterrupted power supply to devices requiring a stable 12V DC voltage. The device is perfect for alarm systems, access control, video surveillance (CCTV), as well as industrial automation applications. It provides a current efficiency of up to 15A, allowing simultaneous power supply to multiple receivers.

Design and functionality

The power supply is designed for mounting inside enclosures or on a DIN rail (DIN3 bracket required, available separately). Compact dimensions (214 x 114 x 50 mm) facilitate integration with existing installations. Built-in protections protect both the powered devices and the power supply itself from damage. An LED optical indicator informs about the presence of voltage at the output. The ability to switch the battery charging current (2A/4A) using a jumper allows you to adapt the power supply to the specifics of the battery and application requirements.

Safety and efficiency

The protections used – short-circuit (SCP), overload (OLP), overvoltage (OVP) and over-discharge (UVP) – guarantee safe and stable system operation. Efficiency at 87% minimizes energy losses and reduces device heating, which translates into longer life and lower operating costs. The power supply complies with safety standards and has protection class I. In the event of a mains power failure, the power supply automatically switches to battery power, ensuring the continuity of operation of the connected devices.
