Switching mode buffer power supply HPSB 27.6V/7A/2x17Ah HPSB-24V7A-C

Buffered impulse power supply – reliable power supply for security and automation systems.

The HPSB-24V7A-C buffered power supply is a device dedicated to providing uninterrupted power in alarm systems, access control, video surveillance and other applications requiring a stable 27.6V DC voltage. The design based on advanced impulse technology guarantees high efficiency and reliability. The device is particularly recommended where power outages can have critical consequences.

Construction and functionality

The HPSB-24V7A-C is characterized by a solid construction in a metal housing, adapted for surface mounting. Inside there are two places for 17Ah/12V batteries, which provide long-term backup power in the event of a mains failure. The device offers a wide range of AC input voltage (200-240V), which increases its versatility. A jumper allows you to adjust the battery charging current (0.5A or 1A), adapting it to the specifics of the batteries used. In addition, the power supply has protections against short circuit, excessive battery discharge (UVP), overvoltage and sabotage (tamper switch).

Key features and benefits

• Uninterruptible power supply: Guarantee of continuous operation of connected devices even during power outages.
• High efficiency: Efficiency at the level of 88% translates into lower energy losses and lower operating costs.
• Battery protection: Short-circuit and over-discharge protection extends battery life.
• Optical signaling: An LED indicates the operating status of the power supply and battery charging.
• Installation flexibility: Surface mounting allows easy installation in various locations.
• Charging current adjustment: Adjusting the charging current to the battery parameters ensures their optimal operation.
• Wide input voltage range: Compatibility with various electrical networks.
• Anti-sabotage protection: A microswitch signals an attempt to open the housing, increasing the level of security.

Technical parameters and applications

The HPSB-24V7A-C power supply is primarily used in systems:

• Alarm systems (SSWiN) – ensuring the continuous operation of sensors and sirens.
• Access control – powering card readers, electromagnetic locks and other system components.
• Video surveillance – stable power supply for CCTV cameras and digital recorders (DVR/NVR).
• Building automation – powering controllers, sensors and other automation devices.
• Fire protection systems – ensuring the continuous operation of the fire alarm control panel and acoustic signaling devices.

The device is intended for indoor use, in an environment with a temperature of -10°C to +40°C. The set includes cables for connecting batteries with angular crimp terminals ML062, which facilitates the installation of the entire system.
