Tax included
The HPSG2-12V20A-E switched-mode buffer power supply is a professional power device designed for the highest level of security in alarm systems (SSWiN) and access control (KD). The device is characterized by exceptional current efficiency reaching 20A, which allows for powering extensive installations consisting of many sensors, cameras, digital locks, and keypads. The power supply design is fully compliant with the rigorous EN50131-6:2017 and EN60839-11:2013 standards at Grade 2, which guarantees reliability in professional applications.
One of the key advantages of the product is an advanced energy management system that ensures uninterrupted power supply to devices even in the event of a mains voltage failure. The power supply automatically switches to battery operation, and after the AC power is restored, it intelligently recharges the battery. The user has the option to select the charging current (2A, 4A, or 8A), which allows for optimal matching to the capacity of the battery used (from 7Ah up to 65Ah). A solid, metal enclosure with forced fan cooling ensures stable operation even under heavy load, and numerous protections protect both the power supply and the devices connected to it against failures.
The product offers a wide range of diagnostic functions, including OC-type technical outputs informing about the lack of AC power (EPS) or battery failure (APS). Thanks to the START function, it is possible to start the system directly from the battery without the presence of the power grid. High energy efficiency at the 89% level minimizes heat loss, which translates into a longer service life of electronic components. This is an ideal solution for installers looking for uncompromising quality and full control over the emergency power system.

Software and logic
The integrated microprocessor system of the HPSG2-12V20A-E power supply is responsible for advanced management of the battery charging and maintenance process. The firmware performs a dynamic load test every 5 minutes, verifying the internal resistance of the cells and circuit continuity. Monitoring algorithms continuously analyze the AC input voltage and DC output parameters, immediately activating OC-type technical outputs (EPS, APS) if anomalies are detected. The system protects the battery against deep discharge (UVP) and optimizes the charging current depending on the selected mode (2A/4A/8A), which significantly extends the life of the connected batteries.
