Compact 25 W Enclosed Supply

The Analog Technologies ALRS12V2R2AT is a new 25 W enclosed switching power supply that converts 90–264 VAC to 12 VDC at 2.2 A. Its 1.5 in (38 mm) low-profile metal case includes a built-in fan for full-load cooling from 10 °C to 60 °C. Designed for 3D printers, computers and LED lighting, it meets international safety regulations for industrial use.

Input Range and Surge Limits

The unit accepts a wide 90–264 VAC input, covering both 110 VAC and 220 VAC mains without manual switching. It can withstand a 300 VAC surge for five seconds, protecting against brief over-voltage events. Efficiency exceeds 83 %, so waste heat stays modest at full load. The all-metal enclosure provides full shielding to minimise electromagnetic interference.

Replaces Open-Frame or Lower-Rated Units

This supply upgrades from open-frame modules or lower-wattage bricks that lack an enclosure, fan or 5G vibration rating. The jump is worth it when the install demands a rugged metal housing, built-in cooling and certified surge withstand for continuous industrial duty. It is not for buyers who need adjustable voltage, multiple output rails or higher than 25 W output.

Questions about this item

Is this 12V 2.2A model the right choice for a device that draws up to 25W?

Yes, the unit delivers 12VDC at 2.2A for a maximum of 25W, matching that load exactly.

What does the 25W rating mean when the supply is installed in a 3D printer or LED system?

It means the supply can continuously provide 12V at 2.2A with efficiency above 83%, so the connected device receives stable power while the unit itself wastes less than 5W as heat.

The input range is 90V to 264VAC — does that cover both 110V and 220V mains without a switch?

Yes, the wide auto-ranging input accepts 110V and 220V nominal voltages directly, and it can withstand a 300VAC surge for 5 seconds.
