R-core transformer

This R-CORE transformer is ideal to build a power supply for a DAC or a preamplifier.

It has 2x115V as primary widing. As long as the appropriate wiring is made, it can be used on the European power grid as well as the American grid.

Two secondary windings each provide a voltage 9VAC with a maximum current of 1.66A. Moreover, it is equipped with a magnetic screen and an electrostatic screen.

Each cable is identified by a different color code. This color code is detailed on a label found directly on the body of the transformer.

Dimensions of the transformer

Mounting hole spacing 70x48mm

The values of the secondary voltages of the transformers are the nominal load voltages. The no-load voltages will be slightly higher than those stated.

qualité pas au niveau de ce qu'on attend d'Audiophonics
reperage et qualité des fils de sorties laissant à désirer. Pour cabler en parallele les 2 sorties, il faut faire plusieurs tests et plusieurs mesures. Hum present apres mise en parallele des sorties, donc qualité et symetrie du bobinage pas tres bonne.

très bon choix
Transformateur d'excellente qualité : bon rendement (chauffe très peu) ; écran électrostatique efficace ; tension secondaire qui reste stable à pleine charge et accepte même une petite surcharge momentanée. A recommander sans réserve.

Make a change!
If you working on electronics about 35 years (like me for example) you have a lot of chances to see new things!
One of these things was that, to replace my toroid transformer in my 20 years preamplifier (Diy Hi-End) with R-CORE.
The reasons was two!
First, when i put my ears very close to toroidal trafo, i was hear hum noise!
In the past i never checked to hear that, and second reason after a lot of reviews all around the audio forums, i was thinking that, it is not a bad idea with this little cost to make a change!
Everything for experiments! That's the life!
About results?
The most important there is no hum noise, second i am not sure but i believe something has change to the better way!

good choice
bought this transformer together with the linear power supply 12220 from this shop for an audio streamer made with a raspberry pi 3 and hifiberry dac pro .
it is working perfect for me,no humming or other disturbing noise and enough power to work with raspi,dac and the 7 inch official display.
even that i do not have "golden ears" i was able to hear a difference between this power supply and the Meanwell power supply i used before.
i will buy this transformer again for further projects.
