Cute, thin little PSU
Very thin low power output supply. It only takes up about 3/4″ of rail for the 15W (smallest) version. I dialed it down to 10V for my application and I saw that 9.5 was also within the adjustment range.

Handy power supply
Tidy way to get some 12v signal voltage into an enclosure for triggering small relays and such.

Good Value
This 12v dc power supply has been powering my Lettuce grow controller for months now. Love the capability of it and look forward to using it to power more things. Will update review if anything should happen.

slow rise time can cause trouble, otherwise very nice.
This is a very nice and compact power supply, however the rise time of 80ms is longer than most comparable supplies. This measurement is how long the voltage takes to reach the stated output after the âsetupâ time which is the delay after applying power before it turns on. Depending on your equipment this can cause trouble. I intended to use these to power an ESP32 based GPIO controller and with this power supply after itâs sat for more than a few minutes the ramp up to full power is slow enough to confuse the ESP32 into going into download firmware mode rather than starting up normally. Additional quick power cycles work fine, but it seems that once the internal caps in the power supply have discharged completely it just takes too long to ramp up to the full voltage output for my application. It works perfectly every single time with a meanwell DR-15-12 which has a rise time of 50ms or a MDR-20-12 with a rise time of 30ms. This is probably not going to be a problem for most equipment but if you have strange issues at poweron after it has been off for more than a few minutes then this might be the issue and you should try one of the others. It is definitely a problem for at least some ESP32 based devices.

Decent little power supply
This is currently housed in a steel box near the top of a 25′-high gym. The unit has remained stable for several months now. Thermally, little heat is noticed. It’s on 24/7/365, but there’s only a draw on it a couple hours a week, and that draw is around 300 mA. It’s used as the PSU for a DIY 0â10V/DMX switcher design, driving both a DMX converter and a relay board.

Perfect
I love these meanwell power supplies, I have at least 15 of them in use. Consistent power, and cool operation.

Dc voltage wrong
The enclosure said it was 10 to 12 VDC. The Circuit board that was installed was a 15 to 30 VDC so could not use.

works well
All of the Meanwell supplies I bought work perfectly I have used at least a dozen.
