Pros & Cons

Pros

  • ✓ Two full 350.4W units per order, so you get a matched spare
  • ✓ 24V at 14.6A suits stepper drivers, LED tape, and arcade chassis
  • ✓ Universal input: 90-132 VAC and 180-264 VAC, no regional SKU swap
  • ✓ MEAN WELL LRS-350 is a part number integrators already spec by name

Cons

  • ✗ Single fixed 24V rail only, no 12V or 5V output for mixed-voltage builds
  • ✗ Bare enclosed frame with screw terminals, not a plug-in adapter
  • ✗ Requires you to wire your own AC mains input lead
  • ✗ Exposed terminal block means it needs an enclosure for safe use

Manufacturer description

The Mean Well LRS-350-24 is the workhorse enclosed switching power supply that retro PC builders, arcade cabinet restorers, and LED-strip installers keep specifying by part number, and this listing ships two of them. Each unit delivers a single 24V DC rail rated at 14.6A, for 350.4W of continuous output from the LRS-350 family. The universal input range covers 90 to 132 VAC and 180 to 264 VAC, so the same supply drops into a 115V North American bench or a 230V European one without sourcing a different SKU. That 24V rail is the standard feed for stepper drivers on CNC and 3D-printer builds…

Frequently Asked Questions

How many power supplies come in this order?

Two. This listing is a 2-pack of the Mean Well LRS-350-24, each rated 350.4W at 24V.

What voltage and current does each unit output?

Each unit puts out a single 24 VDC rail at 14.6A, which works out to 350.4W of output power.

Will it run on 230V European mains?

Yes. The input range is 90 to 132 VAC and 180 to 264 VAC, so it accepts both 115V and 230V mains.

Does it come with a power cord or plug?

This is an enclosed frame supply with screw terminals rather than a cord-and-plug brick. Check the product listing for what ships in the box.

Is this the right supply for a 24V LED strip or stepper motor setup?

The 24V at 14.6A rating covers most 24V LED tape runs and stepper driver setups under 350W per unit. Budget your load against that 14.6A ceiling.
