Mine let out the magic smoke one day and stopped working. I was going to order a similar one so it could be installed into the original power supply case then decided no I'll buy a better one and print a replacement case to fit this to the printer.
This units fan is quieter, the heat controlled fan feature works and its a Mean Well so the odds of a failure from it burning the workshop down are less.

I had no issues with these power supplies. I operate a HF amateur radio within the same room and was expecting some electrical noise from the PS, but have yet to find any.
So, they are quite, in a electrical sense, and work reliably with my home brew 3D printer.

I used this power supply for some Ham radios. It worked well, and seems to power my radio stably. I don't have any insight into RFI since I was just doing some VHF/UHF stuff which isn't as susceptible.

The body is well built, I never heard the fan come on, even after a fair bit of power draw, and the whole thing is utilitarian design, but well built. Just be careful with the power lugs being exposed - it's not particularly safe, although the plastic separators makes it take effort to touch them. I put some electrical tape over the top after wiring it up to make it marginally safer.

There's no power switch. I just pulled the power cable from the wall.

Do note that it doesn't come with any cables (no wall cable, nothing), so you're on the hook for wiring it up to wall power, and then whatever connections you want. I bought an unterminated power cable from home depot to plug into the wall, and some various short jumper wires to the connectors I needed.

Even with the extra cables to buy and the limitations, it worked well and was a fair bit cheaper than a "ham radio" power supply.

This is the power supply that my 3d printer needed. No more shut downs on bed heating do to under voltage issues.

Review of the MEANWELL LRS-350-24 DC switching power supply

TL;DR - The Meanwell power supply (sold by Hybridge) is a solid performer. Nice, slim case, able to fine-tune the voltage, and very clean looking inside. A solid buy.

Received the product in a timely manner. Boxed nicely, and included mounting feet (which is nice). Picture one reflects that. The unit is input voltage switchable (115v or 230v)

The unit internally has a nice clean layout. I did not look on the underside of the circuit board, only the top (pictured) side.

The fan is removable (if you wish to add another). 60mm square, 15 mm thick. There was a mention that the fan seems a bit loud, and I would concur. Also, trying to determine what triggers the fan to come on. The docs seem to indicate based upon thermal temperature, but it would also appear to be based upon current draw. If I pull 6amps on the unit (out of 15) the power supply doesn't get warm however, the fan will kick on anyhow. It does seem variable in that if I decrease the load, the fan slows down. Fortunately, I have this mounted in a closet so it is not noticeable.

One other mention about the fan. It is an ARX DC Brushless, 12v 0.13a, 15 cfm fan. If you google for that fan, it is sold on here for like $24 - $27 (elsewhere $16 to $18). For a basic fan, seems quite high in price considering the noise it produces.

The power supply has external access to a trim-pot allowing to tweak the desired voltage. I took several voltage measurements of the unit itself (One of the pictures I combined all the differences to). Ultimately, there is a +/- of almost 5v swing.
For a brief, I observed the following:

24.19v - out of the box measurement
20.89v - Adjusted all the way down
29.94v - adjusted all the way up.

Upper-right image on the measurement picture was just me setting it to 24v when I was done measuring.

There are 6 terminals for output (3 for positive(+), 3 for negative(-)). There are three terminals for the main voltage (Neutral, Line, ground). About the only ding I give here is that unlike other power supplies on the market, the Meanwell does not come with that little plastic swing cover to cover over the terminals.

I have a 6 amp load of LED strips, and wanted something that could handle double-that in the future, so I ended up with the 15amp (14.6a technically) power supply (leaving me 20% overhead so not ever fully loaded, which is how you should plan your projects). Final two pictures show's the supply working, and my mounted project :)

All in all, I am happy with the purchase. It does what it is supposed-to.
