Buffered SMPS Power Supply Atte AUPS-70-240-XL1 24V 3A 72W (buffered)

Atte AUPS-70-240-XL1 is a buffered SMPS power supply that provides a regulated 24V DC output at up to 3A (72W). The unit combines switch-mode efficiency with an integrated buffering function to maintain output during brief mains interruptions or to support controlled shutdown of connected equipment. Designed for installations that require a compact, reliable 24V source, it suits applications such as access control, CCTV, alarm panels and industrial control modules.

Advantages

The buffered SMPS design delivers stable 24V output with low ripple and efficient energy conversion, reducing heat and power loss compared with linear supplies. Integrated buffering protects against short mains drops and helps avoid unwanted resets of connected devices. The supply’s compact form factor and standardized DC output make it easy to integrate into cabinets and DIN-rail or shelf-mounted setups. Built-in protections typically found in modern SMPS designs help safeguard connected loads against overload, short circuit and thermal stress.

Suitable for

• Access control systems and magnetic lock power feeding
• CCTV cameras and small camera systems requiring 24V
• Alarm panels and security sensors needing continuous power
• Industrial control modules, PLCs and peripheral devices with 24V input

When it may not be suitable

This power supply is intended for devices that require a regulated 24V DC source up to 3A. It may not be suitable for equipment requiring higher continuous current or peak loads beyond 3A, or for systems that need extended backup time during mains failure — the buffering function covers brief interruptions but is not a substitute for a battery-backed UPS sized for long runtimes. Applications demanding specific environmental ratings (e.g., outdoors without enclosure or extreme temperature ranges) should verify enclosure and operating temperature requirements before selection.

Key specifications

• Output voltage: 24V DC
• Maximum output current: 3A
• Maximum output power: 72W
• Buffered output for brief mains interruptions
• Regulated SMPS topology with low ripple output
• Protection features: overload, short-circuit and thermal protection (typical for SMPS)
• Compact form factor for cabinet or DIN-rail compatible installations

How to use

Install the Atte AUPS-70-240-XL1 in a ventilated electrical cabinet or on an appropriate mounting surface, observing polarity when connecting the 24V DC output to the load. Connect the AC mains input to a properly rated supply circuit with protective earthing. After power-up the unit provides a regulated 24V output; the buffering will sustain output during short mains drops and allow orderly shutdown of connected devices if configured. Follow local electrical codes and use suitable wiring, fuses or circuit breakers sized for the expected current draw. For integration into alarm or access systems, route signal and power wiring to minimize interference and ensure reliable grounding.

What to consider before purchase

• Verify that connected devices do not exceed 3A continuous current at 24V
• Determine whether the buffering capability is sufficient for your mains interruption requirements or if a dedicated battery-backed UPS is needed
• Confirm the installation environment (ventilation, enclosure, ambient temperature) and mounting options
• Check required protections and cabling standards for your local electrical regulations

Usage recommendations

For reliable operation, mount the unit in a dry, ventilated enclosure, keep wiring runs short to reduce voltage drop, and use appropriate overcurrent protection. Test the buffered behavior during commissioning by simulating short mains interruptions to ensure connected devices behave as expected.
