heaveno Per -Anderson,

I wanted to use them for a CD player with a CD-PRO2M as Bergrans. http://bergrans.despinnerij.nl/index.php?content=power-supply
I took the components values' from his site: 
http://bergrans.despinnerij.nl/doc/component_list_JSR03.pdf

Sadly none of them works:(:(
The 9v one the tension starts to slowly rise from 8v to 9,6v, afterwards lowering to 8v again. Then, this repeats.
At the 5v module , the exit tension is 3,6v.
Hours and hours I have checked but I found no mistake at the component
connecting.
Do you have any sugestions?
I would have a few questions :
Before the testing do the modules have to be set up on the radiator?
How do you correctly connect the 3mm led(Zener) on the 5v module?
Where exactly do you measure the tension on the exit - on X3-X4-X5 ?

Thanck you!

Best regards,
Vitalie

Have you connected the SENSE inputs? If not, put a tin blob on the solderside.

heaveno ,

The 9v one, after I connectet the R=100 Om at the exit, the tension starts
  to slowly rise from 8v to 9,6v, afterwards lowering to 8v again. Then,
  this repeats.
  At the 5v module , the exit tension on R=50 Om  is 3,6v.

Regards,
Vitalie

What about the sense inputs? Have you shorted them to the output and the ground? How much is your input voltage? Is the H1 lit?

From the picture you have send to me I can see that you never have connected the outputs. Please check the schematic carefully. Output are X4, X5 (plus) and X8, X9 (gnd)

C9 should not be mounted.

R10 should be 0 ohms but 100 ohms is OK.

heaveno Per-Anderson !

I connected X3-X6 , X7-X10.
now, on 9 V module to the out i have 9.11V
and on the 5V module i have 4.95 v.


Is ok?

Best regards,
Vitalie

This seems very good. Try also to load the regulator to see if it's stable.

Glad to hear that it all works for you. I don't mind pictures later but handshake this with me first.
