The music in this video is so calming, I had to watch this video a few times.
This was a joy to watch
Great informational video, thanks for sharing! Took me a few tries to try and stay focused as I kept drifting off into dream land.
This was lovely, and just what I needed. Thank you for sharing the process! ❤
Very clear and helpful. Thank you
Thanks!
Magical❗💡🤙🍄
price value for thsi powersuply kit is unbeatable
You should have those mains wires away from the 12 volt ones
Nah this is so real, mans gonna burn up his modules if not his entire house💀
Over 2 years of using it everyday, zero issues. I'm no expert but it seems obvious to me that if the wires are isolated it's fine, but just to make sure I asked the experts and they said no problem!

I did just that. But I used 2x RT50B to power 4x 84hp with two busboards as I calculated that the RT50B gives ample +12V for 2x 84hp but a single RT65B does not deliver enough -12V for 4x 84hp.
This video is amazing! One question: I didn’t see the ground wire (yellow) connecting to the actual Bus Board? According to the documentation it looks like the bus board has a ground hole that is supposed to be connected to the AC Ground. Is this optional?
Thank you! The ground/yellow wire goes from the power socket to the PSU, then there is also a black wire going from the PSU COM to the GND hole on the actual bus board. The wires are connected exactly as shown in the documentation.
@@DanieleGiannattasio great! Thanks for the clarification! Beautiful video
where did you get the terminal cover?
It will be available on Modular Synth Lab website soon. Check out the description
Do you need a fan to manage heat? Does it get very hot?
No you don't need a fan and it works just fine. I'm not sure if the psu gets hot as it's placed under the modules but I highly doubt it.
Very nice - what's this amazing music?
Thanks. Just randomly playing notes on the "piano" :)
@@DanieleGiannattasio well I'll tell you, it sounds great. Keep it coming!
Do you know when the Power Supply Unit will be availabe again?
No but if you ask them I'm sure they will help you.
The Modularsynthlab Team said the PSU would be availabe again in the second week of February
I might as well ask here, since I dont know where else.
I'm making a DIY synth that only needs +12 -12, no 5v required
i would absolutely use this power supply, but after looking at the datasheet, it has really low amp ratings for the -12 rail, like half an amp. (then i would need multiple of these to make the full thing)
does anyone know a good alternative with higher amp ratings?
Sorry I can't help with the choice of another PSU, but I know that this one can deliver up to 3,5A at +12V and 1A at -12V lines as long as it can "borrow" the extra power from the 5V line. You may try asking on Mod Wiggler, where I'm sure more people will be able to help you quickly.
@@DanieleGiannattasioah yeah, that is better to know. thank you for that advice and clarity, and.. speed of responding lol
Where did you find the instructions from Modular Synth Lab?
My order came without any documentation or instructions whatsoever.
There should be a picture showing the connection scheme on the kit's page.
@@DanieleGiannattasio Thanks. I totally missed this. It would have been hellpfull earlier today 😄.
Is the terminal cover file available on thingiverse or somewhere else?
It will be available to purchase from the website linked in the description. You can contact them to ask :)
@@DanieleGiannattasio Ok thanks i will do so. I don’t really accept buying such a small piece of plastic and shipping it around half of the earth 😅
@@felixXawesome if you only need that, I guess you might find similar terminal covers for the Mean Well PSU if you search on Google
@@DanieleGiannattasio Yeah I did 😅 no success so far 😅
What brand are the surface mount electrolytics?
Can't really tell... maybe you can take a look at the bus board on their website or contact them directly.
Thanks Daniele. I'll take a look. I thought you might work for modularsynthlab yourself :) Cheap Chinese electrolytics have a habit of dying early, especially with the heat contained inside a case so want to make sure they are a decent brand.
@@theguvnor2081 no I don't work for them :) I don't know if they are good quality capacitors but I'm using this kit since I filmed the video and it works just fine. Bobeats has also been using these for a while in his big case, hopefully that's a good indication of longevity!
The guys at modularsynthlab told me that they aim for either Nichicon or Panasonic caps, or at least automotive grade depending on availability. If that's true then it should be decent enough.
what model is the Meanwell?
Mean Well RT65B, every part is linked in the description.
thanks @@DanieleGiannattasio
that power supply is big enough to power like 9u 104hp easily? just get multiple bus boards? How does the system sound compared to Behringer CP1A or Tip Top power supply? Is there more noise or different character? Just wondering how smooth the DC signals are.. if they are audiophile or not.
I guess it depends on the total power consumption of your system but I believe you might need a second PSU. By the way this one delivers +12 3.5A, -12V 1A, 5V 2A.
I did not compare the two side by side but I didn't notice any difference when using the same modules with both CP1A and Mean Well. I used it with a lot of different modules from various different brands and I have experienced zero noise whatsoever.
@@DanieleGiannattasio Thanks for the reply. I think I might get the Mean Well power supply for my little eurorack module development station I want to build with jacks, siwtches, knobs and breadboards.,
what are the dimensions of the case ?
6U / 84HP, 9 cm internal depth.
Thank you !@@DanieleGiannattasio
Thanks for explaining nothing with the actual wiring but the stock piano was exactly what I was looking to hear at this moment (sarcasm) .
I'm sorry your expectations were not met and I regret to inform you the piano is not stock :) regarding the wiring, unless you are colorblind, it should be pretty easy to mimic what I did in the video. That said, if you click the first link in the description, you will find a picture with the same exact colored wires and an idiot-proof (I hope) wiring scheme. Considering your low level of attention though, I suggest you not play with a PSU unless you are supervised by your parents (sarcasm).
There's not much to explain really. If you have some basic understanding of electronics, you can easily do this since there is no actual building of circuits involved. That's why there's no need for a tutorial or explanations. If you need a tutorial to follow along, you shouldn't be handling PSU parts by yourself and just buy a ready made solution. You're looking at 110-230V AC strait from your mains here. If you make a mistake, you might as well put a screwdriver in your wall outlet ;)
