Fonte de alimentação comutada com buffer PULSAR AWZG2-12V2A-B 12V 2A

PULSAR AWZG2-12V2A-B is a switching buffer power supply that delivers a regulated 12 V DC output at up to 2 A. It is intended to power and stabilise low-voltage electronic devices commonly used in security and access control installations. The unit combines voltage regulation and buffering to keep connected equipment operating smoothly during short transient disturbances and brief power interruptions, making it suitable for systems that require a steady 12 V supply and short-term backup capability.

Advantages

The switching design provides efficient conversion with reduced heat compared to linear supplies, while the integrated buffer function keeps output voltage stable during momentary input fluctuations. Compact construction and standard mounting options allow easy integration into control panels or enclosures. Built-in protections typically included in this class of supply help prevent damage from overload and short-circuit conditions, supporting reliable continuous operation of security and access devices.

Suitable for

• Powering security cameras and surveillance modules that require 12 V DC
• Supplying access control systems such as electric locks and readers
• Feeding low-voltage sensors, detectors and alarm control panels
• Use as a buffered power source in installations with occasional mains disturbances

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 2 A
• Supply type: switching (switch-mode) buffer power supply
• Intended use: low-voltage electronics, security and access control
• Functionality: voltage regulation with short-term buffering for transient stability

How to use

Install the power supply inside a suitable enclosure or control panel following local electrical regulations. Connect the mains input and the 12 V DC output to the load using appropriately rated wiring and secure terminals. Verify correct polarity before powering connected devices. Ensure adequate ventilation around the unit and avoid mounting near heat sources. If the installation includes batteries or additional backup components, follow manufacturer instructions for safe connection and charging management.

Recommendations

For reliable performance, use cable sizes and fusing appropriate for the 2 A maximum output and limit continuous load to within the rated current. Periodically inspect connections and enclosures for signs of wear or overheating. When integrating with alarm or access control systems, coordinate buffering and backup arrangements so devices receive stable 12 V power during brief mains interruptions.
