Dell ALT-2402 24 V power adapter

The Dell ALT-2402 is a 48 W AC to DC power adapter that delivers a stable 24 V output at up to 2 A. It accepts a universal 100 to 240 V AC input at 50/60 Hz and terminates in a 5.5 mm × 2.5 mm barrel connector with centre-positive polarity. A compatible 2.1 mm inner-diameter tip is also supported.

Suitable for 24 V devices up to 2 A

This unit suits LED strip lighting, CCTV cameras, small DC pumps and fans that require exactly 24 V and draw no more than 2 A. It will not suit equipment rated for 5 V, 12 V, 19 V, 36 V or 42 V, nor devices whose peak current exceeds the 2 A limit. Buyers needing higher wattage or a different voltage should look at alternative power supplies.

Bundled barrel connector simplifies wiring

A female DC barrel connector is included so that bare wires can be secured by screw terminals without soldering. This accessory speeds up installation for custom wiring jobs and reduces the chance of loose connections in permanent setups.

Questions about this item

What mains voltage range does the ALT-2402 accept for worldwide use?

The adapter accepts 100 to 240 V AC at 50/60 Hz, so it works on mains supplies worldwide without a voltage selector.

My device has a 5.5 mm × 2.1 mm barrel jack — will the supplied plug fit?

Yes, the DC plug has a 5.5 mm outer diameter and an inner diameter of 2.1 to 2.5 mm, making it compatible with both 2.1 mm and 2.5 mm centre pins.

How can I verify the adapter is delivering a stable 24 V output after connecting it?

Measure the output with a multimeter set to DC volts; you should read approximately 24 V with the centre pin positive and the barrel negative.
