Hello Velleman,
I soldered the K8004 Kit, but it doesn´t seem to work. I checked every soldering point and the resistors as far as possible.
I used an external voltage source as well as the internal reference voltage, but the controller passes the Input Voltage directly to the Output Connector. There ist no regulation at all. It does not react on any potentiometer input.
Do you have any hints for further toubleshooting? How can I check the IC or the Diodes?
Thanks for your help
-> Is there a chance that your Tech Support can check the module? I bought it in Germany from Conrad Electronics.
