Switched-Mode Buffer Power Supply PULSAR HPSG2-12V2A-B 12V 2A, buffer output

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.
