Review on Mean Well LRS-350-24 24V πŸ’‘ 14.6A 350W DC Switching Power Supply by Jerry Eintertainment

Solid actor. Nice clean design.

MEANWELL LRS-350-24TL;DR Switching DC Power Supply Overview - Meanwell Power Supply (sold by Hybridge) is a reliable manufacturer. Nice thin body, the ability to fine tune the tension and a very clean appearance inside. Reliable purchase. Receive the goods on time. Nicely packaged, the legs are included (which is nice). The first picture reflects this. The device has a switchable input voltage (115V or 230V). The unit has a nice clean interior. I didn't look at the bottom of the board, just the top (pictured) side. The fan is removable (if you want to add another one). Square 60 mm, thickness 15 mm. It has been mentioned that the fan seems a bit noisy and I agree. Also try to determine what is causing the fan to turn on. The docs appear to show based on thermal temperature, but this also appears to be based on current draw. When I pull 6 amps (out of 15) into the unit, the PSU doesn't get warm, the fan turns on anyway. It seems variable in the sense that the fan slows down when I reduce the load. Luckily I put it in the closet so it's not noticeable. Another mention from a fan. This is ARX DC 12V 0.13A 15cc brushless cooling fan. feet per minute. If you google this fan, it sells for $24-$27 here ($16-$18 elsewhere). For a basic fan, this seems like a pretty steep price to pay considering the noise it makes. I made several measurements of the tension of the block itself (in one of the pictures I combined all the differences). Ultimately there is a +/- swing of almost 5V. Briefly, what I observed is: 24.19V - standard reading 20.89V - set all the way down 29.94V - set all the way up. The top right picture in the measurement picture was simply that I set it to 24V when I was done measuring. There are 6 output terminals (3 for positive (+), 3 for negative (-)). There are three main power terminals (Neutral, Line, Ground). The only issue I'll raise here is that unlike other power supplies on the market, Meanwell doesn't come with that little plastic flip-up cover that covers the ports. twice as much in the future, so I opted for a 15 amp (technically 14.6 amp) power supply (which left me with 20% overhead so I was never fully loaded, so plan your projects). The last two photos show the working delivery and my assembled project :) Overall I am happy with the purchase. He does what he has to.
