Buffered switch-mode power supply with technical outputs PCSB 13.8V/3A/7Ah PCSB-12V3A-B

Buffered impulse power supply – reliable power for your devices

This buffered impulse power supply, with an output voltage of 13.8V DC and a current of 3A, is an ideal solution for alarm systems, video surveillance, access control and other devices requiring uninterrupted power. The device provides stable voltage and protects connected devices from the effects of voltage drops in the network. Thanks to the built-in charging circuit, the power supply works with 7Ah or 9Ah batteries, automatically switching to battery power in the event of a network failure.

Functionality and safety in one device

The power supply is equipped with a number of protections that protect both connected devices and the power supply itself from damage. These include short-circuit protection (SCP), overload protection (OLP), overvoltage protection (OVP) and undervoltage protection (UVP). Additionally, it has a tamper-proof protection (TAMPER) that signals an attempt to open the housing. Two AC FAILURE and BT LOW VOLTAGE relay outputs inform about network failure and low battery charge, allowing for a quick response and preventing downtime in system operation.

Installation and operating comfort

The RAL9003 plastic housing is designed for surface mounting and has adjustable cable glands to facilitate connection of wires. The LED optical signaling indicates the operating status of the device. High efficiency (88%) translates to lower energy losses and lower operating costs. The power supply is designed for continuous operation and has a two-year warranty confirming its high quality and compliance with European standards. Please remember that installation should be carried out by a qualified installer in accordance with applicable regulations.
