Review on πŸ’‘ MEAN WELL NES-350-12 12V 350W UL Listed Switching Power Supply 110-240V by Dominic Ceo

Revainrating 5 out of 5

SO SO SO glad I paid the extra 25% or so and bought it.

WOW SO VERY glad I paid the extra 25% or so and bought this model over one of the really cheap ones. This is a really high quality well made block that doesn't cut corners. The chassis is all aluminum and everything is solidly built. The terminal blocks are easy to use and have the right dimensions. I use it to power 4 different R/C chargers at the same time and it makes it easy to max out at about 0.2 volts of sag from the set value (adjustable with a screw), even at 75% of rated power. ENSURE YOU HAVE SET THE SWITCH ON THIS UNIT TO THE CORRECT LINE IN. Mine came on the 240v position and I didn't notice. I plugged it in and at first it seemed to work fine, but even with a minimal current draw of a few amps, the voltage dropped 3+ volts. I was ready to send it back until I saw the switch and realized my idiocy. I unplugged it, waited a few seconds, flipped the switch, plugged it back in and it's been working like a brick ever since.

Pros
  • Forced air cooling with built in DC fan
Cons
  • Not as thick as other models
