## Summary description

Switch-mode power supply (SMPS) Atte 21365 provides 24 V DC output at up to 3 A (72 W). Designed for low-voltage devices and control equipment that require a stable 24V supply, it suits CCTV systems, access control, industrial controls and LED lighting. Compact SMPS topology ensures regulated output and efficient operation for continuous or standby use.

## Long description

The Atte power supply SMPS 24V 3A 72W (model 21365) is a compact switch-mode power supply that delivers a regulated 24 V DC output with a maximum current of 3 A and a continuous power rating of 72 W. It is intended for low-voltage devices and control equipment that require a stable 24 V source. The unit uses SMPS topology to provide efficient conversion from AC mains to DC, supporting continuous operation or standby duty in applications such as CCTV, access control panels, industrial control modules and LED lighting loads.
Advantages
The SMPS design provides higher efficiency and lower heat dissipation compared with linear supplies, reducing energy losses during extended use. Its compact form factor saves installation space and allows mounting in cabinets or junction boxes. Built-in voltage regulation helps keep output stable under varying load conditions, and protective features typically found in SMPS units — such as overload and short-circuit protection — contribute to reliable operation of connected equipment.
Suitable for
CCTV camera systems and network video recorders requiring 24 V DC power
Access control panels, electric strikes and door controllers
Industrial control modules, sensors and PLC peripheral devices
LED strips, signage and low-voltage lighting fixtures designed for 24 V input
When it may not be suitable
This SMPS is not intended for devices that require voltages other than 24 V or for loads that continuously exceed 3 A (72 W). It may not be appropriate where an isolated or medically certified power source is required; check device specifications for special isolation, medical safety or EMC requirements before use.
Key specifications
Output voltage: 24 V DC regulated
Maximum output current: 3 A
Maximum output power: 72 W
Topology: switch-mode (SMPS) for efficient AC to DC conversion
Intended use: continuous or standby low-voltage power supply
How to use
Install the power supply according to local electrical codes and the manufacturer’s mechanical mounting instructions. Connect the AC mains input to the designated terminals with correct supply voltage and protective grounding where required. Connect the 24 V DC output to the load observing correct polarity. Verify the combined current draw of connected devices does not exceed 3 A. Allow adequate ventilation around the unit and avoid mounting directly against heat-sensitive surfaces. If multiple loads are connected, consider inrush currents and distribution wiring to prevent voltage drops.
What to consider before purchase
Confirm connected devices require 24 V DC and have a combined current draw at or below 3 A
Check whether isolation, surge protection or specific safety certifications are required for your installation
Ensure available mounting space and ventilation meet the unit’s installation needs
Usage recommendations
For reliable operation, place the power supply in a dry, ventilated location, protect the AC input with appropriate upstream fusing or circuit breakers, and use properly rated wiring for the 24 V output to minimise voltage drop. Periodically inspect connections and ensure the load remains within rated limits to extend service life.
