Meanwell 24V SMPS with AC Cord
1 x Meanwell GST120A24-P1M Power Supply
1 x US/CA/MX/JP (Type B) power cord
This high quality 24VDC SMPS is Nelson Pass's recommended power supply for the Amp Camp Amp.
A 6' power cable is included with your selection of US/CA/MX/JP (Type B), EU (Type E), or AU/NZ (Type I) AC plugs. If you have a different plug type in your country, you likely have a spare in your parts bin.
Why this power supply?
Nelson Pass tested several candidates for the Amp Camp Amp, and this Meanwell GST120A24-P1M power supply had the best performance of all the candidates. Compared to the previous power supply, this one:
- More power - about 7wpc
- Improves signal to noise ratio
- Runs cooler
- Comes with a 3 year warranty from a trusted brand

Who is it for?
It is a suitable upgrade for all previous, current and future planned generations of ACA (see note below), and will plug straight in to all previous Amp Camp Amp DC jacks.
It will also drive several other as-yet-undeveloped amps we have on the drawing board for the future. You can consider it an investment in a quality 24VDC power building block that will not be made obsolete for a long time.
About the manufacturer
Unlike most PSU manufacturers, 99% of MeanWell's business comes from sales of power supplies bearing the MeanWell name. Over 40 years, they've grown to be the 5th largest PSU manufacturer in the world, and the only one in the top 5 who sells supplies using their own brand name.
The result is a brand that has become synonymous with quality and you can be assured that purchasing this PSU is a long term investment in quality power for your projects, and testament to that is the fact that they back this PSU with a 3 year manufacturer warranty.

In fact I'm using 2 of them running two amplifiers as dual monos
This SMPS does a very good job powering the AMP CAMP AMP.
I'm using the 24vd version and the power supply/amp couple plays music which sounds simply amazing.
I'm very pleased with the whole setup
The power supplies are hidden so they cannot be seen, sorry
This PS solved a bad noise problem....worth every penny!
Je suis vraiment satisfait de cet achat. Le kit et les explications sont d’excellentes qualités, continuez comme cela c’est parfait.
Je suis ravi par l’écoute des amplis, la musique n’en est que plus belle…
Je suis déjà entrain de me demander si cela vaut la peine de réaliser un autre de vos projets.
After still being very impressed with my first ACA amp I have built a second one, to be given to my brother. I didn’t have any problems with the build in fact I made a neater job of it than my first one. I am amazed at the bass response for such a low powered amp and I also find the treble so sweet and not fatiguing.
I got the meanwell with my ACA and it is very clean. I’ve tried it with a couple cheap Amazon amps that also take 24v and it removed a ton of noise that apparently was coming from their cheaper power supplies. Works great with the ACA as well.
Does the job and very well. Thought that a large transformer, large capacitors, and the other items would be missed, but not so. Nice peace of mind to have most of the PS chain out of the chassis and away from the audio components.
