Switching buffered power supply HPSB 27.6V/3A/2x17Ah HPSB-24V3A-C

Buffered power supply – reliable power supply for security and access control systems

This buffered impulse power supply, model HPSB-24V3A-C, is a solid solution for systems requiring continuous power, such as alarm systems, access control, or video surveillance. The device provides a stable voltage of 27.6V DC with a maximum current of 3.5A, and the built-in battery charging circuit allows for a smooth transition to battery power in the event of a mains power failure. The power supply design is intended for easy installation and integration with existing systems.

Construction and functionality

The HPSB-24V3A-C power supply is a high-efficiency (87%) impulse device, which translates to lower energy consumption and less heat loss. The housing is made of DC01 steel (1mm) powder-coated in white (RAL 9003), providing durability and corrosion resistance. Inside, there are two spaces for 17Ah batteries, which allows for extended system runtime in the event of a power outage. The use of SCP (short-circuit), OLP (overload), OVP (overvoltage), and UVP (deep discharge) protections guarantees safety for both the device itself and the devices connected to it. Additionally, the built-in tamper switch signals an attempt to open the housing, increasing the security level of the installation.

Key features and benefits

• Buffered power supply: Ensures continuous operation of systems even during power outages thanks to support for two 17Ah batteries.
• High efficiency: 87% efficiency minimizes energy losses and reduces operating costs.
• Versatile protections: SCP, OLP, OVP and UVP protections protect against damage caused by short circuits, overloads, overvoltages and deep battery discharge.
• Tamper signaling: Built-in tamper switch informs about attempts of unauthorized access to the device.
• Adjustable charging current: The ability to choose the battery charging current (0.5A/1A) allows you to adjust the parameters to the specifics of the batteries used.
• Solid construction: Durable steel housing provides durability and resistance to mechanical damage.
• Easy installation: Designed for surface mounting – quick and convenient installation in a selected location.
• Wide range of applications: Ideal for alarm systems, access control, video surveillance and other devices requiring a stable emergency power supply.

The HPSB-24V3A-C power supply is a reliable solution for both professional security system installers and end-users looking for a proven emergency power source for their devices.
