Grade 2 buffered switch-mode power supply, HPSG2 13.8V/20A/65Ah HPSG2-12V20A-E

Reliable power supply for alarm and access control systems

The HPSG2-12V20A-E buffered switch-mode power supply is a solid solution providing uninterrupted power for burglary and assault alarm systems (SSWiN) and access control (KD) systems. The device, designed in accordance with EN50131-6:2017 and EN60839-11:2013 standards, guarantees a stable 12V DC voltage (+/- 15%) even in the event of a mains power failure. This purpose makes it an ideal choice for both professional installers and end-users who value the safety and continuity of their systems.

Design and functionality

The HPSG2-12V20A-E power supply is characterized by high efficiency (up to 89%) and the ability to select the battery charging current (2A / 4A / 8A). It is equipped with a START function, allowing manual switching to battery power. LED optical signaling informs about the device's operating status, and protections against deep battery discharge (UVP), short circuit (SCP), and overvoltage (OVP) protect both the power supply and connected devices. Additionally, a built-in tamper switch signals an attempt to open the housing, increasing the level of security. The housing made of DC01 steel sheet (RAL 9003 color) ensures durability and resistance to damage. Thoughtful housing dimensions (460x390x173+14 mm) allow for easy mounting and convenient cable routing.

Parameters and applications

The HPSG2-12V20A-E power supply offers a maximum output current of 20A, allowing it to power even extensive alarm or access control systems. The ability to connect a battery with a capacity of up to 65Ah ensures long-term backup operation in the event of a power failure. The device finds application in securing:

• Alarm control panels
• Motion sensors
• Coded locks
• Surveillance cameras
• Alarm manipulators
• Intercoms
• Access control systems

Thanks to compliance with European standards and high-quality workmanship, the HPSG2-12V20A-E power supply is a guarantee of reliability and security of your system. Remember to provide proper cooling of the device during operation!
