Re: power supply btc 03v0 is it bad?
You were right, its not the power supply, the problem is the serial interface card witch seems to be sorted. I will try to find the problem and I will inform you for the result... if I am lucky... The company sell refurbished interface boards for 500$!!Leave a comment:

Re: power supply btc 03v0 is it bad?
Sorry for the delayed answer. I dont have the cameras with me, I will check them and I will inform you as soon as I go to the garage.
Let me tell you also, that when I plug the cameras, the voltage there is 11.97vdc as I told you before. The camera start autocheck (beeping, lights flashing) and suddenly go off. I check the voltage again, and it is still 11.97. I tryed it with all 4 cameras, same thing happens.Leave a comment:

Re: power supply btc 03v0 is it bad?
Do you think I will have any luck by changing the voltage regulator and gain a few cVs? Is it possible for the cameras to fail due to such a small difference?Leave a comment:

Re: power supply btc 03v0 is it bad?
Thanks For your quick reply.
My problems are:
1) My transformer is nf540-7612 and I dont know if there is a diference between nfs40 and nf540.
2) The laser cameras connected to the serial board start and then shut down immedistely. It seems to be a power issue.
Is it possible the 11.97vcd instead of 12vcd to create such problem?
The cameras are really sensitive equipment, and I am afraid to use another power supply if I am not sure 100%.Leave a comment:

power supply btc 03v0 is it bad?
Hello dear friends.
This is my first thread, and I hope I will take an answer for my problem.
In a car wheel aligner named "bear" I have an issue with the power supply. It is the one mentioned in the title, and the board number is "510132 rev k".
I cannot find any informations on this besuse it has so many different types in the same module.
I am having output dc 14.7vdc and when I plug it to the serial interface card it as 11,97vdc. I cannot find anywhere what is the correct output dc voltage. Can someone please help?
Thanks in advance -

Hello from me too.
My name is Babis and I am from Greece. I am an enthousiast with electronics, since I was a child. My first project, when I was 9, was to convert an old car cassette player to a guitar amplifier, and totally by accident, it worked! Since then I started to try repairing all kinds of electronics. I am an amateur, and I try to read a lot about electronics. Best fixes ever: Car ECU's, medical equipments, many cell phones and tablets and many many laptops.
