Meanwell 24V 5A power supply and power cord

  • 4900



Description

This is Nelson Pass's recommended power supply for the Amp Camp Amp. Now available for immediate sale.

It gives you more power and less noise than previous power supplies. It's a serious unit - twice the size and twice as heavy as the previous one.

This is a high quality 24V universal SMPS. It takes an input of 86-264VAC at 47-63HZ via a standard IEC320-C14 "Kettle Plug" AC inlet. It outputs 24V via a P1M Barrel Connector.

A 6' power cable is included fitting 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'll need to borrow an IEC cord ("kettle plug") from your least favorite piece of equipment or use a plug adapter.

Why this power supply?

Nelson Pass tested several candidates for our "new and improved" Amp Camp Amp power source, and this Meanwell GST120A24-P1M power supply had the best performance of all the candidates. Compared to the old power supply, this one:

  • More power - about 7wpc
  • Improves signal to noise ratio
  • Runs cooler
  • Comes with a 3 year warranty from a brand well known to be one of the most reliable in the industry
 

 

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.

Notes for upgrading to 24V from 19V previous generations of ACA

"You can use also this supply on the original ACA, but you will want to adjust the DC value on the output up to 12V. You can also adjust the feedback resistor and bias resistors down to the values of the ACA 1.5."

To use the 24V PSU and also bring your ACA up to new 1.6 specification:

  1. If you have a PCB that says revision 1.0, add bias resistor R15 (increases power to 6W)
  2. If you have 1.0 or 1.0b, adjust R12 from 68k to 39.2k
  3. If you have 1.0, 1.0b or 1.1, adjust the DC value on the output to 12V

A real high level power supply

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

Great little power supply

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.

Meanwell 24V 5A Power Supply

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.

ACA order and build

Diyaudio is great, shipping is very fast, kit was fun to build and the amp sounds great! Currently attempting to build the ACA+ preamp wish me luck finding and ordering all the parts is a challenge for a newbie like me.
