Invisus ultra super regulator
 
Quote:

PPR1 (positive) and NPR1* (negative) utilise a high speed and ultra low output impedance FET and guarantees peak current demands are instantly and effortlessly met. This coupled with our propriety self noise cancelling system give Invisus DC regulators outstanding resilience, reliability and performance.
Those nice words are for the Audiocom's super regulator Invisus. Anybody who knows more what's all about? I wonder also if a marketing person with or without technical insight has wrote this. Some people are good with words but what is really true and what does it mean?

There other super regulator was just a plain Sulzer regulator so I get a bit suspcious although it looked very nice.

Picture here

Judging by the price...they are at least twice as good as the plain Sultzer regulators. :angel: :cannotbe:
By the way..what is a Sultzer regulator?




[edit] added the smilies to try to show my sarcasm..

you can attain better noise levels with an LT431 /LM329DZ and an MJD44H11 -- for about $2.00 -- and even some of the stock Linear Tech and TI regulators will beat their advertised noise levels (and probably superior in several other aspects as well.)

Nothing is parted more quickly than a fool and his money.

I just read the pcb text: Designed by J Cheat !

A Sulzer is a ship diesel engine, i guess this thing does not regulate diesel engines ?
How about a diyaudio low noise regulator design, and flogg it for serious cash ?
PPR, "Positive Power Regulator sounds nice".

opamp fed from the unregulated side
the reference is fed from the regulated side
feedback
single emitter follower as series element.

David Sulzer wrote about long time ago therefore people here call it "The Sulzer Regulator".

Why do people say Sultzer/Jung?
