Buffered switch-mode power supply for installation PSB 27.6V/3A PSB-24V3A

Buffered switch-mode power supply – reliable power supply for your system

The PSB 27.6V/3A buffered power supply is a solid solution for providing uninterrupted power to devices requiring a stable 24 V DC voltage. The switch-mode design guarantees high efficiency, and the ability to charge the battery ensures continuous operation even in the event of a mains power failure. This is an ideal choice for both professional installers of monitoring, alarm systems, and for users looking for a reliable power supply at home or in the office.

Functionality and safety in one device

This power supply is distinguished by its high efficiency of 87%, which translates to lower operating costs. It has built-in protection against short circuits (SCP), overloads (OLP), overvoltages (OVP), and excessive battery discharge (UVP), protecting connected devices and ensuring safe system operation. The ability to switch the battery charging current (0.5A/1A) allows you to adapt the parameters to the specifics of the battery used and optimize the charging process. Additionally, the presence of optical LED signaling informs about the status of the power supply – the presence of AC and DC voltage and the battery charging process.

Flexible mounting and wide application

Compact dimensions (159 x 98 x 42 mm) allow for easy mounting in limited space. The power supply can be mounted for built-in installation or optionally on a DIN rail using an appropriate bracket. A wide input voltage range (200-240V AC) ensures compatibility with most electrical installations. The device is used in CCTV systems, access control systems (ACS), burglar and fire alarm systems (SSWiN), video doorbells and other applications requiring stable and reliable 24V DC power. The total output current is 3.5A, which means that with the battery charging current set to 0.5A, the available output current is 3A, and with the setting to 1A – 2.5A.
