Buffer power supply PULSAR HPSG3-24V5A-D 24V 5A, buffered DC output for security and access systems

PULSAR HPSG3-24V5A-D is a buffered power supply that delivers a stable 24 V DC output with a maximum current of 5 A. Designed for security, alarm and access control systems, this unit provides continuous regulated DC power and buffering to maintain device operation during short mains interruptions. The compact, enclosure-ready design allows integration into control panels or rack installations where a reliable 24V source is required for cameras, control panels, electromagnetic locks and other low-voltage devices.

Advantages

The unit provides regulated 24 V DC output with built-in buffering to bridge brief power outages, reducing false alarms and maintaining system availability. Its rated 5 A output supports multiple devices simultaneously while voltage regulation protects connected electronics from fluctuations. The design includes thermal and overload protection for safe continuous operation and a compact footprint for straightforward installation in equipment cabinets or distribution boxes.

Suitable for

• Security alarm control panels and sensors
• CCTV cameras and camera junction boxes
• Access control panels and electromagnetic locks
• Low-voltage automation modules and relays

Key specifications

• Output voltage: 24 V DC (regulated)
• Maximum output current: 5 A
• Buffered/backup output to maintain supply during short mains interruptions
• Protection features: overload and thermal protection
• Mounting: enclosure or panel-mount compatible compact design

How to use

Connect the mains input according to local electrical regulations and wire the 24 V DC output to the system load, observing correct polarity. If the installation requires battery buffering, connect the recommended standby battery type externally following the manufacturer’s instructions for safe charging and connection. Verify output voltage and load current are within device limits before final commissioning. Ensure protective fusing and earth connection are in place according to installation standards.

Usage recommendations

Install the power supply in a ventilated enclosure away from direct heat sources, and route cables to minimise interference. Regularly inspect connections, battery condition (if used) and ventilation paths. For extended backup or higher current demands, consider using appropriately rated external batteries and distribution arrangements to match system requirements.
