Mean Well LRS-350-24
350 W of clean 24 V from mains for bench testing. Every robot project eventually needs a power supply that can feed the motors on the bench without a battery in the loop.
The role it plays
Power sets the ceiling on everything else: peak torque (voltage × current), runtime (watt-hours ÷ average draw) and safety. Size the bus voltage to your actuators, size the pack to your worst-case current, and put protection upstream of the pack — before, not after, the first puff of smoke.
Typical use: Bench testing motors, charging, permanent installs.
What the numbers actually mean
The headline figure is 100 – 240 V AC (input), with 24 V, 14.6 A as the next most load-bearing number (output). At $35 in the power tier it sits in the mid range: enough money that you should plan the mounting and wiring before ordering, but not so much that one mistake ends the project.
How it compares
Same subsystem, closest alternatives. The primary spec column is usually the one that decides it.

Where it shows up
It is a component-level choice rather than a defining part of a named platform — pick it for the subsystem it serves, not to match a reference build.
