Buffer power supply Grade 2 AWZG2 27.6V/2A/2x7Ah AWZG2-24V2A-B

Backup power supply for alarm and access control systems.

The AWZG2-24V2A-B backup power supply from Pulsar is a reliable device designed to provide uninterrupted power to burglar and intrusion alarm systems (SSWiN) and access control (KD) systems. The device stabilizes the voltage to 24V DC, guaranteeing continuous operation of connected devices even in the event of a mains power failure. The power supply complies with EN50131-6:2017 and EN60839-11:2013 standards, confirming its high quality and safety.

The microprocessor-based automation system used in the power supply monitors the battery status, controlling its voltage, circuit continuity and state of charge. The START function allows manual switching to battery power, which is particularly useful during maintenance or system testing. Additionally, the power supply has OC (EPS – AC mains failure, APS – battery failure) technical outputs, which inform about any power supply problems. The housing made of DC01 steel sheet (RAL9003) ensures durability and resistance to mechanical damage.

Key features and benefits

• Compliance with standards: Meets the requirements of EN50131-6:2017 and EN60839-11:2013 standards, guaranteeing its use in professional security systems.
• Voltage stabilization: Provides stabilized 24V DC voltage (+/- 15%), protecting connected devices from damage caused by voltage fluctuations.
• Buffer and battery operation: Automatically switches to battery power in the event of a mains power failure, ensuring continuous system operation.
• Battery status monitoring: Monitors battery voltage, circuit continuity and state of charge, informing about the need for replacement or maintenance.
• OC technical outputs: Allow remote monitoring of the power supply status (AC mains failure, battery failure).
• Protections: Has short-circuit (SCP), overload (OLP), overvoltage (OVP), undervoltage (UVP) and anti-tamper protections.
• Battery space: Designed to work with two 7Ah/12V batteries, providing long-lasting backup power.
• Long warranty: 5-year manufacturer's warranty confirms the high quality and reliability of the device.

Technical parameters and application

The AWZG2-24V2A-B power supply is ideal for use in alarm systems, access control and other applications requiring reliable emergency power. The output current of 2A allows you to connect many devices simultaneously. The ability to set the battery charging current (0.5A/1A) allows you to adapt the operating parameters to the specifics of the installation. Surface mounting simplifies installation and access to the device if necessary. A distance of 8mm from the ground provides convenient cable routing. The use of high-quality components guarantees long life and trouble-free operation of the device for many years.
