Switched-mode buffer power supply HPSB 13.8V/7A/17Ah HPSB-12V7A-C

Buffered power supply – reliable power for your system

The HPSB-12V7A-C buffered switch-mode power supply from Pulsar is a solid solution designed to provide uninterrupted power to devices requiring stabilized 12 V DC voltage. It is ideal for alarm systems, access control, video surveillance (CCTV) and other applications where continuous power supply is critical. In the event of a mains power failure, the power supply automatically switches to battery power, guaranteeing trouble-free operation of connected devices.

Design and functionality

The HPSB-12V7A-C power supply is characterized by high efficiency (87%), which translates to minimal energy losses and stable operation in various conditions. It is equipped with a space for a battery with a capacity of up to 17 Ah, which provides long-lasting backup power. The metal housing (RAL 9003 color) not only protects the internal components from mechanical damage and interference from third parties, but also allows for surface mounting. Additionally, the housing has a distance from the wall to facilitate cabling.

The power supply offers a number of protections that protect both the installation itself and the connected devices: short-circuit (SCP), overload (OLP), overvoltage (OVP) and against battery discharge (UVP). The built-in anti-sabotage microswitch signals the opening of the housing, increasing the level of security. The LED optical signaling informs about the operating status of the power supply and battery charging. The battery charging current can be adjusted using a jumper (1A or 2A).

Parameters and application

The power supply operates in the input voltage range of 200-240 V AC and provides an output voltage of 13.8 V DC with a maximum current of 7 A. The total current of receivers together with the battery charging current should not exceed 7 A. This makes it possible to power multiple devices simultaneously and charge the backup battery. The use of high-quality components and advanced technologies ensures reliability and long life of the device. It is an ideal solution for both professional security system installers and end users looking for a reliable power source for their devices.
