Switched-mode buffer power supply HPSB 13.8V/3A/17Ah HPSB-12V3A-C

Buffered power supply – reliable power for your system

This pulsed buffered power supply, model HPSB-12V3A-C, is a solid solution for systems requiring stable and uninterrupted power. It is ideal for CCTV, alarm, access control, and intercom systems. The device provides 13.8V DC with an output current of up to 3A, and also offers battery charging function. Therefore, in case of mains power failure, the system will switch smoothly to battery power, ensuring continuous operation.

Construction and functionality

The power supply is housed in a durable metal enclosure (RAL9003 – white color), designed for surface mounting. Inside there is space for a battery with a capacity of up to 17Ah, which allows to extend the system operating time in case of power failure. The housing has a tamper switch, signaling an attempt to open it. LED optical signaling informs about the device operating status. The use of a pulse power supply module translates into high energy efficiency – as much as 87%.

Safety and protection

The HPSB-12V3A-C power supply is equipped with a number of protections to protect both the installation itself and the connected devices. These include: short-circuit protection (SCP), overload protection (OLP), overvoltage protection (OVP), and excessive battery discharge protection (UVP). Additionally, a tamper protection is used, which informs about an attempt to unauthorized access to the device. A built-in varistor protects against AC mains voltage surges.

Key features:

• Wide input voltage range: 200-240V AC – ensures compatibility with most electrical installations.
• Stable output voltage: 13.8V DC – guarantees correct operation of connected devices.
• Output current: up to 3A + 0.5A battery charging – allows powering various devices with different power consumption.
• Battery space: 17Ah/12V – provides long-lasting backup power.
• High efficiency: 87% – minimizes energy losses and reduces operating costs.
• Protections: SCP, OLP, OVP, UVP, tamper – protect against damage and ensure safe system operation.
• Metal housing: provides durability and resistance to mechanical damage.
• Surface mounting: facilitates installation and servicing of the device.

The HPSB-12V3A-C power supply is a reliable solution for both professional installers of security and CCTV systems, and for end-users looking for a stable and safe power source for their devices.
