NewTesla, you said your supply was +/- 60V.
the spec sheet for that supply shows +/-75V - did you have them change this for you? if so, did the mod cost?
This power supply looks pretty ideal for my project, which is a combined 3 channel amp to run a pair of mains - BFM DR200's from a Truepath - and a mono Sub channel - currently a pair of BFM Autotubas from a UcD400 module.
cheers

Hi,
I'm not NewTesla but I will give some info on my experienced with the vendor.
I think the spec. that is published is the old one, because when they sent me the connection diagram, the output voltages were: +/-80V, +/-30V, +/-12V and 12V for fans.
I requested to lower the 80V to 55V and isolate the +/-12V to be used for Truepath, that is no cost to me. I think most modification are free as long as there is no substantial amount on parts added to it.

can anyone who has used this power supply with a truepath give details of deriving the 5v and 10V supplies from it? the 5V is referenced from ground, but the 10V is ref'd from the -ve rail, so they both cant come off the 12v supply. i was thinking the 30v supply could provide the 10V requirement, and the 12v supply the 5V one.
but if someone could knock up a quick circuit diagram, and let me know what I need to tell Red Rocks to do to the supply, i would be much indebted.
cheers,

Here is an example for wiring SMPS to Truepath from RedRocks.

Interessting, they also have wiring diagramms for Hypex amps:

+/-30V seems not ideal for UCD180 imho. I would also like to know the max current the smps can deliver for +/-30V and +/-60V.

thanks for the links to red Rock's circuit diagrams
I just ordered one of these supplies, and the cost was US$204 plus US$60 shipping to australia.
you need to request them to modify the supply to suit a truepath (60V rails, floating 12v supply) - which they do at no cost.
Im going to be running both a truepath and a UcD400 from one of these supplies, whioch since both use 60v rails, is not an issue. Im not sure if they can modify the 30V rails, but it would certainly be interesting to know.
a version of this supply that could deliver +/-60V AND +/-80V would certainly be interesting, but probably pushing the limits of the design. im thinking Truepath driven main speakers, plus UcD700 driven subs...

However, REDROCKSAUDIO
Manufacture those in CHNINA (MASS PRODUCTION) they say its made in Spain, and orginally REDROCKSAUDIO are SELLING those PRODUCTS from ANOTHER COMPANY.
I dont like there approach in dealing with people. They dont respond properly
I just got a reply from Jose
Appears Red Rocks has merged with another company and is no longer manufacturing the miniPROC. However, Jose did give me a method for restoring the USB boot loader. I'm going to try it now and see if it works, I can post if anyone's interested.
P.S. apologies for hijacking the original thread - my bad
P.P.S. I'm also using their SMPS which I must say is working flawlessly & very quiet!

How did you test it to know, exactly what kind of fact is that?
Without data it's only an opinion.
But to answer your first question, I bench tested it into a variety of resistive loads up to 50W looking at input & output volts & current and monitoring the output voltage on a scope. This gave me efficiency and ripple in best case scenario.
Then I bench tested it with 3 ucd180 modules, again into resistive loads using music and sinusoid test stimuli to see what dynamic loading was like and build confidence before applying to speakers.
Since then I have power cycled the thing in the full system countless times over the past 3 months, tweaking the system and it has never popped, crackled, whined or buzzed. All the smoke is still inside.
But what I like best is how quiet the ucd modules are with this supply. Now, they're also quiet with the Hypex SMPS and probably others that I haven't tried, but all these mix/mash ups are still quieter (listening test) than my old school class B's on a giant toroid.
