Author emitum thin and clean power case!
koobraelc
I spend time to develop this power board and case that can fit what I need. The case called "sán-sán".
It looks pretty like usual 2x84hp case but has some good features and detail with sán-sán.
It's really thin, lightweight, and with low ripple power. sán-saán provide a really affordable price for everyone who love modular.

Lightweight
It made by aluminum with high quality coating, and only weight 2.3kg/5lbs.

Low Noise
performance of power board at typical current consumption(1000mA):


(Power ripple lower than 10mV)




+12V measurement


-12V measurement

Installation and Equipments

    1. Passive Voltage Probe: Tektronix TPP0500B
    2. Oscilloscope: Tektronix MDO3054
    3. Programmable DC Electronic Load: Chroma 63600-5
    4. AC Power Supplies: KIKUSUI PCR2000LE
    5. Data Acquisition Switch Unit: Keysight 34972A
    6. *DC Power Adapter: Mean Well Desktop AC Adapter GST60A24-P1J





    1. Programmed DC Electronic Load in constant current mode.
    2. Increase 5mA of current consumption every 50 seconds.
    3. Measure data at each step.
    4. Stop measurement after 3.3Hr while current achieve 1.2A.
    5. Restart another measurement keep this procedure for three times.
    6. Data sorting and analysis.


Low-cost
It will start pre-order at $329USD.
It's cheapest same-stage eurorack case in the market right now.


Spec:
Space: 84hp x 2 (M3 rails)
Weight: 2.3 kg / 5 lbs (without power adaptor)
Size(w/ Lid): 428mm (l) x 268mm(w) x 113mm(h)
Size(w/o Lid): 428mm (l) x 268mm(w) x 58.6mm(h)
Depth: 52mm
+12V: 1200mA
-12V: 1200mA
+5V: 1000mA

dang, this looks very very nice!!!, too bad my deepest module is 60mm :( Are you planning on deeper version too?

nice cool

You mean inner 60mm?

yes inner, i might switch that module with other that is not as deep, my other modules are no deeper than 40mm, so all of them should fit fine as your case is 52mm deep. But if the deeper case is possible, i would be interested in a fatter one hehe.

What is the deepest module depth in all positions (what is the measurement over the top of the power supply heat sink)?

The measurement graphic refers to max power consumption as 1000mA, but the specification list 1200mA.

How hot does the power supply get?

Is the DC converter brick included? What does it look like?

What is the coating material used, and how durable is it?

How do you use the included audio ports? How are they connected to your module?

Where do you ship from?

Thanks! The case looks very nice!

I need to re-mesure all position. Will keep update detail sketch in this post.

I update more detail above!

No, not included (to lower the selling price)

Anodize with spray painting.

I will release IO expand module. It will has inner link cable.

geremyf wrote:

Taiwan.

Update:

It would have 84hp and 104hp as options!

I'm also thinking to release the spec of IO board that everyone can design their own IO module. SlayerBadger!
funken
nice case, 104hp can be great...
funken
if any of you use this case, I am curious to have some feeback... and pics.

We have a table at TFoM Rockin' Banana! Rockin' Banana! Rockin' Banana!

Got some really nice feedback. 104hp is also ready to run first production!!!

looks really cool. great to see your taking advantage of the cheap manufacturing options in TW, when I lived over there that was a great benefit.

I just wonder tho for som of the people outside of TW, will the additional cost make it a less effective option,

also, will you be able to use another brick to increase the power?
at 22 headers you may have to selective choose what you put in there to stay around the 80% mark, no?

also as for constructive criticism
id say for your next round you may consider the 1u addition.
mostly because its trend, from what I can tell most of the new designs all have that, and although it does of course add to the price, the option for 1u tile utilities which (usually) run a bit cheaper that there 3ster counterpart. its a cost/space effective solution for many folks

that all being said and taken in to consideration I like the case and would consider it but when you add all the little details up the case is really cool but may turn out to be around the same cost as some other the other options that are out there in regards to "priced for what you get"

Nice work. Looks like Intellijel’s thinner brother without the 1U

It's possible, but can guarantee the stability.

It's true, but what type of 1U everyone prefer? Intellijel or Monome.

i stay away from tiles, the euro format is small enough as it is. but man it really sucks we even have to ask that question.. that argument has been beaten to death, so i'll move on.

my question is would you consider a 12u? i realize the support and linkage mechanism is a whole new design aspect, but that'd be sweet. i use power modules because i cram lots in there and typically need more power connectors, so consider an unpowered version as well.

The Earthenvar i.e. not the Intellijel version.

-the one 1u deal as previously stated is a horse and carrot...
preference thing.
maybe it'd be possible to put a slotted hole on the case for one of the rails and a rubber bushing to allow for adjusting one of the 2 1u rails, to fit either.. id guess it'd be stable enough. IDK though on aluminum.
- for the cost effectiveness.
I mean shipping, brick, additional features etc.
wasn't meant to be a negative comment just that when you add things up you may wind up at the same price.
- for power that just seems a bit thin for 22 headers. particularly if your planning on using small modules that allow for plenty of extra space and then jumping cabling a FBB or passive board.

I have had the 84HP case for a few weeks now and absolutely love it!

Super portable, really light, very sleek and reasonably priced!

Perhaps I'm a bit biased also being based in Taiwan, but definitely check them out.

+1 for making a 7U (3U + 1U + 3U) 104 HP version. Make the 1U row Pulp Logic format, as almost every other case only caters for intelligel format.

Power-wise I would want something like (12V/-12V/5V) 2A/1A/500mA.

It seems like a good idea. Thanks for the advise! SlayerBadger!
