Product information

Description

The Atte AUPS-40-120-XL1 is a buffered SMPS power supply that delivers 12 V DC with a maximum current of 3.5 A and rated output power of 40 W. Engineered for installations that require a stable low-voltage source, this unit provides continuous 12 V output with buffering functionality to sustain the supply during brief mains interruptions. The compact design and standard connector set make it suitable for integration into CCTV systems, access control panels, alarm equipment and other 12 V device installations where an uninterrupted 12 V feed is required.

Advantages

The buffered output protects connected devices from short power interruptions by switching to the internal buffer without interrupting the 12 V output. The SMPS architecture offers high efficiency and reduced heat generation compared with linear supplies, while the rated 40 W capacity supports multiple low-voltage devices simultaneously. Built-in regulation ensures a steady 12 V output under varying load conditions, supporting reliable operation of cameras, control modules and alarm panels.

Suitable for

  • CCTV cameras and video recording equipment
  • Access control systems and electric locks
  • Alarm panels and sensors
  • Small network devices and low-voltage peripherals requiring 12 V

Key specifications

  • Output voltage: 12 V DC
  • Maximum output current: 3.5 A
  • Rated output power: 40 W
  • Buffered output to maintain supply during short interruptions
  • Switch-mode power supply topology for higher efficiency
  • Compact form factor suitable for equipment racks and enclosures

How to use

Install the Atte AUPS-40-120-XL1 according to local electrical regulations and the mounting requirements of your enclosure. Connect the AC input to a correctly rated mains source and verify correct grounding. Attach the 12 V DC output to the load using appropriately sized wiring and ensure polarity is correct. Check that the total connected load does not exceed 3.5 A (40 W). After powering up, verify the output voltage and observe device operation to confirm stable supply and buffering behavior during any short interruptions.

Usage recommendations

For best performance, place the power supply in a ventilated location away from direct heat sources, use short, adequately gauged cables for the 12 V output to reduce voltage drop, and ensure the combined load stays within the rated limits. Regularly inspect connections and grounding to maintain reliable buffered operation for CCTV, access control and alarm systems.
