Ultracapacitor Power Supplies are coming (PURE-DC-4EVR: the MINI and the MEGA) !

All,

Since LIO was introduced in 2014, I have received numerous requests for a dedicated DC power supply product that uses the same patent-pending, isolated, ultracapacitor-based power supply technology ("PURE-DC-4EVR").  You can learn more about it, here:
http://www.vinnierossi.com/lio-technology/

Such an isolated power supply would be used to replace the stock “wall-wort” power adapter that is used to feed generally smaller products that input a DC input voltage.  For example: the Sonore microRendu and other small computer modules, USB cards, dacs, preamps, headphone amplifiers, and even small amplifiers, and other products & DIY projects requiring fairly low DC voltage(s). Even some CD Transports, turntable motors, and field-coil drivers run on 12Vdc, for example.

I am excited to announce that I now have such a supply available:

MINI PURE-DC-4EVR

Product details and information can be found, here:

Wow, that's awesome Vinnie!  I think others that aren't LIO customers will be amazed at how your technology (and customer service) is second to none.   :thumb:


Love my LIO's!

-  Built-in linear regulated charging circuit (no SMPS or DC-DC converter circuits used)

Vinnie, first, congratulations on this and thank you!  I know there is a lot of DC powered stuff out there that will benefit from this.  I wouldn't be surprised if you had all your black lightning customers lining up to upgrade as well!  Something that popped in to mind - don't the King Sound electrostats run on low voltage/current DC power bricks?  Imagine ESLs running on pure DC!  :guitar:

The line above intrigued me.  Does that mean that there will be no wall wart power supply required for the mini at all; just AC wall outlet - power cord - mini - DC output?  If so, is this built-in something that you are considering bringing to LIO or can't all that extra goodness fit in the box?

Thank you, JJ!

You are correct!

No - that cannot fit in LIO.  LIO uses a 24V, 5A supply.  If using a linear supply, it's too large to fit in there.

Could the MEGA be configured to power the DHT LIO filaments and charge the LIO?  That would be badass me thinks.  :green:

Hmmm, sounds like a nice upgrade for my Mytek Brooklyn  :thumb:

Wish I had this before the LIO.  Would have been the perfect power supply for all DC powered components.

Hi jtwrace,

YES for providing an output for running the DHT PRE filaments.  NO for charging the LIO (LIO needs 24Vdc, but the modules
for the MEGA will be able to output in the range of 3.3Vdc to 18Vdc).

Hi SlushPuppy,

It looks like the Brooklyn runs on 12V, 6A.  The MEGA will be able to take care of that (but the MINI is limited to 2.5A max output).

Vinnie, do you think the mega will have enough juice on tap to run the DHT plus a few other smaller items, or will it be only able to run the DHT if configured to do that?  I was thinking if it could run the micro rendu (or another DC powered streamer) that it could work around needing the modded power output added to the DAC making future modular DAC upgrades easier for some customers.

(BTW, being able to run the DHT on ultracaps is pretty darn awesome!)

(oh, and I just took a minute to look; the kingsound esl run on 11-15v, 120mA DC supplies.  That would be something fun to hear, I think.)

Hi JJ,

Yes, it should be fine to run the DHT PRE and some other small things with the MEGA.  I would have to first do some testing here to be sure, but I think it would work well.

Will you make a 230 V EU version?

Will you make a 230 V EU version?

Hi esmit,

Welcome to Audiocircle and the VR forum!

Yes, there will be a 110 - 120Vac version, and a 220 - 240Vac version.

I put the question of how much current the Mytek Brooklyn needs to their tech support. Answer:
Hi Jim

We are recommending minimum 3A/12V power supply. Some people at computer audio file forum swear that external power supply make huge difference but you must check it by yourself.

Best regards
Kamil

Note that the Sbooster folks claim their BOTW P&P ECO 12V – 13.2V can drive the Brooklyn:

So, I think Vinnie's new PS is still in play for the Brooklyn.

Hi Jim,

I just saw that link and they say:

For this test we use our Sbooster iKnow (red LCD) device. We have checked the power consumption for 10 – 15 minutes. The power consumption of the Mytek Brooklyn is 10 - 12W (44.1 – DSD) without headphone usage.

If this is true, the MINI will be fine as it can deliver 12V and up to 2.5A (30W) continuous.  Cool  8)

UPDATE 9/12:

This week I'll be ordering a few PCBs to test the new board layout for the VR MINI.  I hope to see them sometime next week.  :hyper:
If everything goes according to plan, I should be able to open it up to VR MINI pre-orders at the end of this month...

I'm in on this to power the microRendu.

Hi kdbrink et al,

I'll be posting more about the VR MINI soon.  I have boards coming at the end of this week and I'll be testing.  If
all goes well, I'll have a pre-production prototype ready for RMAF next week.  I'll use it to power my microRendu in
the exhibit room (room 7004).

So far, so good!

All,

GOOD NEWS!  I built a VR MINI board and all is working out fine (after some debugging of the firmware).

I will have a prototype VR MINI at RMAF this week (powering a microRendu, and a CD transport) via
it's isolated, silent-switching, ultracapacitor circuit and super-regulated output stage!  8)

After the show, I'll have a better idea on when we'll be taking pre-orders and getting ready for production.

So far, so good!

This is GREAT news!  Look forward to seeing the MINI pics from RMAF.

Congrats Vinnie!

Have a great show and hopefully we can get together later this month.
