Buffered switch-mode power supply Grade 3, HPSG3 27.6V/2A/2x17Ah/LCD HPSG3-24V2A-C-LCD

Reliable power supply for security and access control systems

The Grade 3 pulse buffer power supply, HPSG3 27.6V/2A, is a device designed to ensure continuous power supply in alarm systems, access control and other applications requiring high reliability. Thanks to the use of advanced technology and a solid construction, it guarantees a stable output voltage even in the event of a mains power failure. Designed to work with batteries with a capacity of up to 17Ah (x2), it provides long-term power backup, which is crucial for maintaining the functionality of security systems.

Functionality and safety in one device

The HPSG3-24V2A-C-LCD power supply stands out with a wide range of protections – against short circuit (SCP), overload (OLP), overvoltage (OVP) and undervoltage (UVP). Additional tamper protections (opening the housing and detaching from the wall) increase the security level of the installation. The built-in microprocessor monitors the status of the power supply and batteries, automatically compensating for temperature changes during charging. Optical signaling on the LCD panel informs about the current operating status of the device, and OC technical outputs allow integration with monitoring and failure notification systems. Remote monitoring via LAN or RS485 interface (requires appropriate modules) allows for a quick response in the event of problems.

Specification and application

The power supply complies with EN50131-6 (degree 1-3) and EN60839-11 standards, which confirms its high quality and reliability. Designed for surface mounting in a metal housing (RAL 7016 color - gray), it provides easy access to connections and maintenance. Thanks to the START function, it is possible to manually start the power supply from the battery in emergency situations. The device is characterized by high efficiency (up to 83%) and low output voltage ripple, which affects the stable operation of connected devices. The power supply is ideal for alarm systems, access control, video surveillance and anywhere a reliable emergency power supply is required.
