## Summary description

Switched-mode buffer power supply PULSAR HPSG2-12V2A-B provides stabilized 12 V DC output at up to 2 A and includes buffer functionality for backup operation. Designed for continuous supply to security, access control and low-voltage electronic devices, this compact unit converts AC mains to a regulated DC source and maintains output during short interruptions when paired with an external battery.

## Long description

The PULSAR HPSG2-12V2A-B is a switched-mode buffer power supply that delivers a stabilized 12 V DC output with a maximum current of 2 A. Designed to supply continuous power to security equipment, access control systems and other low-voltage electronic devices, this compact unit converts AC mains voltage into a regulated DC source. The integrated buffer function enables the supply to maintain output during short mains interruptions when an appropriate external battery is connected, making it suitable for installations requiring brief backup capability.
Advantages
This PULSAR buffer power supply provides stable voltage regulation, efficient AC-to-DC conversion and a compact form factor suitable for constrained installation spaces. The built-in buffer function allows seamless transition to battery-backed operation for short outages, while protection features typical for this class of units (such as overload and short-circuit response) contribute to reliable operation in continuous-use applications. Low standby power consumption and compatibility with standard 12 V devices simplify system design and integration.
Suitable for
Powering CCTV cameras and video recorders that require 12 V DC
Supplying access control panels, electric strikes and RFID readers
Feeding alarm systems, sensors and detectors in security installations
Providing regulated power for small electronic devices and controllers
Key specifications
Output voltage: 12 V DC
Maximum output current: 2 A
Switched-mode (SMPS) topology for efficient conversion
Buffer (battery-supported) output for short backup operation
Compact enclosure suitable for surface or cabinet mounting
Designed for continuous operation with low-voltage electronics
How to use
Install the unit according to local electrical codes and the mounting requirements of the installation site. Connect the AC mains input to the designated terminals and verify correct wiring before applying power. Connect the 12 V DC output to the load, observing polarity. For buffer operation, connect an appropriate external battery to the buffer terminals using correct polarity and cabling; the unit will maintain output during brief mains interruptions when the battery is present and charged. Verify output voltage with a multimeter and test the system under expected load conditions.
Usage recommendations
Place the power supply in a ventilated location away from heat sources and moisture. Use battery types and capacities recommended for backup duration requirements and ensure regular battery maintenance. Confirm that the combined current draw of connected devices does not exceed the 2 A rating to prevent overload. Periodically inspect connections and test buffer operation to ensure reliable performance.
