Switching buffered power supply HPSB 27.6V/5A/2x40Ah HPSB-24V5A-D

Buffered Switch-Mode Power Supply – Reliable Power in Every Situation

This HPSB 27.6V/5A buffered power supply is a solid solution for systems requiring continuous power. Designed to operate in both buffered and battery modes, it provides a stable 24V DC voltage, protecting connected devices from power outages. The power supply design allows for the installation of batteries with a capacity of up to 40Ah, guaranteeing long-term backup operation.

Design and Functionality

The HPSB power supply is characterized by high efficiency (up to 90%), which translates to energy savings. The metal housing (RAL 9003) ensures durability and resistance to mechanical damage. Built-in protections – SCP (short-circuit protection), OVP (overvoltage protection), OLP (overload protection), UVP (deep discharge protection), and tamper – guarantee the safety of the installation and connected devices. An LED indicates the power supply's operating status, and a potentiometer allows for precise adjustment of the output voltage in the range of 27V-28.8V DC. The ability to select the battery charging current (0.5A/2A) using a jumper allows you to adapt the parameters to a specific battery type.

Applications and Benefits

The HPSB power supply is used in alarm systems, video surveillance, access control, and other applications where reliable power is critical. Thanks to the ability to operate in buffered and battery modes, it ensures continuous operation even during power grid failures. Installation is simple thanks to screw terminals for power, output, and battery cables. It is worth noting the dimensions of the device – 460 x 390 x 173+14 mm – which should be considered when planning the installation. The power supply is compatible with batteries with a capacity of 7Ah, 17Ah, 28Ah, and 40Ah, providing great flexibility in choosing the right solution.
