Switched-mode buffer power supply HPSB 27.6V/5A/2x17Ah HPSB-24V5A-C

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

The HPSB 27.6V/5A buffered power supply is a device dedicated to providing uninterrupted power to alarm systems, access control, video surveillance and other devices requiring a stable 24V DC voltage. The design based on impulse technology guarantees high efficiency and reliability. The ability to connect two 17Ah batteries ensures long-term backup operation in the event of a mains power failure.

Construction and functionality

The device is characterized by a solid metal housing (RAL9003), adapted for surface mounting. Inside there is space for two 17Ah/12V batteries, which allows to extend the system operating time in case of a power failure. The power supply is equipped with a number of protections, protecting both connected devices and the installation itself – against short circuit (SCP), overload (OLP), overvoltage (OVP) and deep battery discharge (UVP). Additionally, the presence of a tamper switch (microswitch) signals an attempt to unauthorized opening of the housing. A jumper switch allows you to adjust the battery charging current (0.5A or 2A), adapting it to the capacity and type of batteries used.

Key features and benefits

• Reliable power supply: Provides a stable 27.6V DC voltage, essential for the correct operation of security and access control systems.
• Buffer and backup operation: Automatically switches to battery power in the event of a mains power failure, guaranteeing continuity of operation.
• High efficiency: Impulse technology translates into minimal energy losses and reduced operating costs.
• Versatility: The ability to connect two 17Ah batteries allows you to adjust the hold-up time to individual needs.
• Safety: SCP, OLP, OVP and UVP protections protect devices from damage caused by improper installation operation.
• Anti-vandalism: Tamper switch signals an attempt to open the housing, increasing the level of security.
• Easy installation: The housing adapted for surface mounting facilitates installation.
• LED indication: LEDs inform about the operating status of the power supply and battery charging.

The HPSB-24V5A-C power supply is a solid solution for professionals involved in the installation of security systems and for users looking for a reliable power source for their devices. Thanks to the wide range of protections and configuration options, it guarantees stable and safe operation for a long time.
