Buffer power supply Grade 2 AWZG2 13.8V/5A/40Ah AWZG2-12V5A-D

AWZG2 Series Buffer Power Supplies – Reliable Power for Security Systems

The AWZG2-12V5A-D buffer power supply is a device designed to provide uninterrupted power to burglar and assault alarm systems (SSWiN) and access control (KD) systems. It provides stabilized 13.8V DC voltage, and its construction meets the requirements of EN50131-6:2017 (degree 1 and 2) and EN60839-11:2013 standards, guaranteeing high reliability and safety. The device is perfect for installations requiring a high level of security as well as standard monitoring systems.

Design and Functionality

The power supply is characterized by a solid construction based on a metal housing (RAL 9003), which ensures durability and resistance to mechanical damage. Inside the housing there is space for a battery with a capacity of up to 40Ah, which allows for long-term operation in the event of a mains power failure. A microprocessor-based automation system takes care of optimal battery charging and its condition, performing regular dynamic tests. Additionally, the power supply has protections against short circuit (SCP), overload (OLP), overvoltage (OVP), and excessive battery discharge (UVP), protecting both connected devices and the battery itself. A built-in tamper protects against unauthorized opening of the housing.

Indicators and Communication

The AWZG2-12V5A-D is equipped with LEDs indicating the operating status: presence of AC mains voltage, AUX output voltage, and battery charging status. There are also OC type technical outputs (EPS – AC power failure, APS – battery failure) enabling remote monitoring of the power supply status by the alarm or access control system. Optical signaling and technical outputs allow for a quick response in the event of problems with the power supply or battery.

Key features:

• Compliance with standards: Meets the requirements of EN50131-6:2017 and EN60839-11:2013 standards, ensuring a high level of security.
• Versatility: Designed for SSWiN and KD systems requiring stabilized 12V DC voltage.
• Efficiency: Output current of 5A allows powering even more demanding devices.
• Battery capacity: Space for a battery up to 40Ah provides long-term backup operation.
• Protections: SCP, OLP, OVP, UVP and tamper protect devices and the power supply itself from damage.
• Signaling: LEDs and technical outputs enable remote monitoring of the operating status.
• Automation: Microprocessor system takes care of optimal battery charging and condition.
• Solid housing: Metal housing ensures durability and resistance to mechanical damage.

The AWZG2-12V5A-D power supply is a solid solution for professionals installing security systems and for users looking for a reliable power source for their devices.
