My Original CR-10 S5 power unit exploded or had a melt down. this one went right it without issues and works great. It's even a little smaller that the original, so there is more breathing room inside the control unit.

Did your 3D printer’s power supply fail? This item may be your best choice. First be sure of the voltage you need. The circa 2019 printers often used 12v supplier. New printers typically use 24v supplies. Be sure of which one you need. If you live in the US you would be wise to get a UL listed supply such as this one. This one is UL listed. Most are not. This supply is quiet and has a reputation for safety.

To be fair, I only had this for about 2 weeks. Been using it daily with my ham radios and has worked great, though I have only pushed the supply no more than 15 amps. It stays cool where the fan doesn't even come on, I'm assuming there is a heat sensor to activate the fan when the unit gets warm. As a ham radio operator, this supply works fine for me, no birdies or noise detected on HF, and nothing noticed on the Spectrum Scope Display on my radio. I did hear very minor "hash" below 3MHz that was corrected with a .05uf capacitor.

Have always ordered Meanwell LRS series SMPS when I had a preference. Might cost a bit more than competitors, but overall quality and consistency have been high and found them to be quite reliable. The only problems that I have had is when I personally created the problem. Have yet to damage a supply to point of performance degradation, despite the outright abuse in temperatures above design spec, running right on ragged edge of current limits. Have not seen any issues with EMI / Electrical Noise.

I am a radio amateur (Ham) that operates on the High Frequency (H.F.) Band, (80 to 10 Meters). Most other switcher type power supply's that I previously used or tested have put out Radio Frequency Interference RFI (AKA "Birdies") in the HF Amateur radio bands. I have tested this power supply with a 27Amp resistive load, a O'scope and Spectrum Analyzer and have found, NO dectable H.F. Birdies. The power supplies voltage output is screwdriver adjustable from 11 to 14 VDC, and is settable for 120 or 20 VAC. This Mean Well LRS 350-12 delivers 348 Watts of clean power, Just add a line power cord, you are ready to go!

I have three older 17A Mean Well power supplies that have been excellent performers. I needed 25A or more for my new ham radio (Yaesu FT-710) so I ordered this one. When I got it, I thought they shipped the wrong item... it's a lot more compact than my older 17A power supplies.I added a power cord to the power supply (you have to provide your own three-prong power cord) and hooked up my radio. No line noise was detected (I do have a single clamp-on mix 31 ferrite bead on my radio's power cord). Nice!

Got this to power my do-it-yourself LED strips on my house. Works great providing a lot of stable power. Fan is noisy, ut only comes on under load when the temperature is high (it’s mounted in my garage).
