Product information

Description

The Buffered Switching Power Supply PULSAR AD-55A 13.8V 3.5A (Mean Well AD-55A) is a compact DC power source that delivers a regulated 13.8 V output with a maximum current of 3.5 A. It combines switching topology with built-in buffering to provide stable voltage for continuous and backup power applications. The unit is intended for use with low-voltage devices where steady DC supply and short-term energy storage are required to maintain operation during transient disturbances or brief mains interruptions.

Advantages

The power supply offers efficient switching regulation that reduces heat generation and improves energy use compared with linear designs. Buffered output ensures that connected devices receive a stable voltage during short mains drops or switching events, reducing the risk of equipment resets. Its compact footprint enables installation in limited spaces or inside equipment enclosures, and the design supports continuous operation for monitoring and security systems.

Suitable for

  • CCTV cameras and video recorders
  • Alarm and access control systems
  • Low-voltage telecommunications and networking devices
  • Small automation controllers and sensors

Key specifications

  • Output voltage: 13.8 V DC regulated
  • Maximum output current: 3.5 A
  • Buffered/backup feature for short-term power hold-up
  • Switching power supply topology for higher efficiency
  • Compact physical design suitable for confined installations

How to use

Mount the unit according to the manufacturer’s mounting requirements and ensure proper ventilation around the enclosure. Connect the AC mains input to the designated terminals, observing local electrical regulations and safety practices. Attach the DC output leads to the device(s) requiring 13.8 V, respecting polarity. If the system includes batteries for extended backup, follow the battery connection and charging guidelines supplied by the equipment manufacturer. After connections are made, power the unit and verify the output voltage and load behaviour with appropriate test equipment.

Usage recommendations

Place the supply in a dry, dust-free environment away from direct heat sources. Regularly inspect wiring connections for corrosion or loosening, and confirm that ventilation openings remain unobstructed to maintain cooling efficiency.
