TOPIC:

So I previously used my DDRC-24 in my car using the MIniDCIsolator and it worked perfectly! However reading the specs on it, its 3W max. Looks like I need around 10W input for the Flex (Digital)?

Any suggestions? I was thinking of using something like this DROK and adjusting it to 12V and 1A which is close to 10W, but not sure thats optimal?

DROK: www.amazon.com/DROK-Adjustable-Converter...e/dp/B07JZ2GQJF?th=1
 

I put my flex in a car , I powered it off a single minidc and it worked, for a little while…

i just purchased 3X minidc and plan on parallel 
the outputs with a Schottky diode between them until I realized something….

16v , 500,000 µF cap or a small super cap should be ample and supply plenty of peak current…

here’s what I think would work fine 
a single minidc and this 

www.amazon.com/Shaluoman-Farad-Capacitor...a%2Caps%2C198&sr=8-8


just make sure to have proper fusing, once charged , this cap will supply hundreds of potential amps instantly…..  a small plastic box would be a good idea and silicone the board down inside it 



that buck converter might work….. I don’t know how it’s isolation works

So was thinking of that or a AC>DC converter for the car such as this: www.amazon.com/dp/B004MDXS0U?ref_=cm_sw_...241R7MHSTWAT7JGN17KP. Seems like it would work?
 

No don’t go 12v to 120vac 

it will have horrendous noise.. that’s probably the worst idea…..


you can put regular car power into it it will just have noise…. I once used two sets of GLI at the output and got rid of noise on a ddrc24…

it just needs isolation, you can ram regular car battery power into it all day…

i would simply buy 3X minidc and parallel the outputs,…. I did and it worked 

I put a three amp Schottky diode on all the negatives on each output  but I really don’t think I needed to do that…. I was just thinking if one goes out it won’t take the others with it 

im 100% confidant 3 minidc in parallel will work perfectly

Thanks Oabe!

I will consider that!

However, what would be really nice is if Mini would build and sell one of these units that would support larger units such as the Flex in a car! They already have several car products so it seems like a great transition to do so now. Not sure I want to pay for 3 of these, but will see. It sounds like yours is working great.
 

There only 15$ lol 

i ran one off a single, it worked fine 
then it stopped…. But only to discover it didn’t blow…. The minidc still works 

I have 3 running it now….. no problems at all 
and super quiet operation….. man the ddrc stuff is ultra quiet with a minidc ……

i wonder if all these home audio folks that complain of humm might benefit from using cleaner dc 

idk 


but I would not let such a cheap silly part discourage you….. 

 

And if your worried about the extra 15$ 

go get a 1/2farad 16v polarized cap and cap the outputs 


you can pick one up for about 8$ 

I would go for another minidc tho

Yea, I only have one so would need 2 more, so $30 plus $30 in shipping. NO worries, can also get on Amazon for the same price so will prob choose one option. Its not that big of a deal, just trying to figure things out. Thanks!
 

What Amazon are u talking about 

a buck converter isn’t an isolator

Maybe I’m wrong , a buck converter uses field effect transistors to regulate voltage…. It’s a switching power supply 

I think that’s a different critter….. idk 
maybe I’m mistaken
