SMPS Power Supply ATTE AUPS-70-120-L1 12V 6A 72W Buffer Power Supply

The ATTE AUPS-70-120-L1 is an SMPS buffer power supply that provides a stabilized 12 V DC output with a maximum current of 6 A and a continuous power rating of 72 W. It is engineered for use in installations that require steady primary power and reliable short-term backup, including CCTV systems, access control panels and other low-voltage security and telecom equipment. The unit integrates protection features and a compact form factor suitable for mounting inside control cabinets or equipment enclosures.

Advantages

This power supply delivers a regulated 12 V output with up to 6 A current, ensuring consistent operation of connected devices. It supports buffering to maintain output during brief interruptions and incorporates overcurrent protection to reduce risk to connected loads. The compact SMPS design optimizes efficiency and heat dissipation while allowing straightforward installation in confined spaces commonly found in security and telecom cabinets.

Suitable for

• CCTV cameras and video recording equipment that require 12 V DC power
• Access control systems such as electric locks, controllers and readers
• Small telecom and networking devices that operate on 12 V
• Control panels and security enclosures needing a buffered 12 V supply

When it may not be suitable

The unit is not intended for high-power devices that exceed the 72 W continuous output or for applications requiring higher voltages. It is also not a long-duration uninterruptible power supply; buffering covers short outages but is not a replacement for extended backup batteries or generators. Applications with specific environmental or ingress protection requirements should verify enclosure and mounting options, as the supply is designed primarily for indoor cabinet installation.

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 6 A
• Maximum continuous power: 72 W
• Topology: switch-mode power supply (SMPS) with buffering capability
• Protection: overcurrent protection
• Mounting: suitable for installation inside control panels and equipment enclosures

How to use

Install the power supply inside a suitable ventilated cabinet or enclosure and secure it according to mounting instructions. Connect the AC input to an appropriate mains supply using correct wiring and protective elements as required by local electrical codes. Connect the 12 V DC output to the load, observing correct polarity. If integrating into security or access control systems, ensure common grounding and verify that total connected current does not exceed 6 A. Test output voltage and protection operation before commissioning the full system.

What to consider before purchase

• Confirm total current draw of all connected devices does not exceed 6 A (72 W).
• Verify that a buffered 12 V supply meets backup duration requirements; consider external batteries for extended autonomy.
• Check installation space and ventilation inside your control cabinet or enclosure.
• Ensure local mains voltage compatibility and compliance with installation standards.

Usage recommendations

For reliable operation, place the unit in a ventilated, dust-free cabinet, keep wiring runs short, use appropriate fuses or circuit breakers on the input and output where required, and periodically inspect connections for corrosion or loosening. When used with camera or access control systems, leave headroom (recommended 20%–30%) between expected load and maximum rated current to accommodate inrush currents and future expansion.
