Dell ALT-2404 96W AC/DC Adapter

The Dell ALT-2404 is a 24V 4A power adapter delivering up to 96W for compatible devices. It accepts 100-240V AC input at 50/60Hz and provides a regulated 24V DC output through a 5.5mm x 2.5mm barrel connector. Safety features include overload, over-voltage, over-current, over-temperature and short-circuit protection. The unit ships with an AC input cable and a flame-retardant housing.

Suits 24V equipment drawing up to 4A

This adapter powers LED strips, CCTV cameras, LCD monitors, massage chairs, 3D printer AMS units, routers, switches and similar 24V loads that do not exceed 96W. The 5.5mm x 2.5mm plug also fits 5.5mm x 2.1mm sockets with centre-positive polarity. It is not for devices that require a different voltage, need more than 4A, use a different connector type, or require battery-charging circuitry.

Deciding spec: 24V DC at 4A max

The single figure that determines fit is the 24V DC output rated at 4A maximum. Your device must list a 24V input and a current draw of 4A or less. If the unit needs higher current, a different voltage, or a non-barrel connector, this adapter will not work.

Questions about this item

What size DC barrel connector does the Dell ALT-2404 use?

It uses a 5.5mm x 2.5mm male plug that is also compatible with 5.5mm x 2.1mm jacks, with centre-positive polarity.

How do I connect the AC side of the adapter?

Plug the supplied AC input power cable into the adapter's IEC inlet, then into a 100-240V 50/60Hz mains socket; the step often missed is seating the IEC cable fully until it clicks.

When should the power cable be replaced?

Replace the 3x 0.75 mm² (18AWG) cable if the PVC jacket cracks, conductors are exposed, or the barrel plug becomes loose or intermittent.
