power supply btc 03v0 is it bad?

[albabis]

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

That looks correct, 14.7 volts unloaded, 12 volts when under load, NFS40-7612J

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%.

Spec on page 2 of the spec sheet, the NFS40-7612J (are you sure that it is NF5, not NFS?)
has output regulation of +/-2% so 11.97VDC output is way within the spec.

yes I am sure. You can see it on the transformer in the middle of the image in my second post.

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?

If your camera does not work due to 3mV drops in voltage (11.97V instead of 12.00V), then you have very very bad camera, more likely that it has problem.
What is the spec of the LASER camera? What are the Voltage and the Current requirement?

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.

Re: power supply btc 03v0 is it bad?

here I am again. I tryed out a few things with the cameras, but nothing seems to work. I also took a picture from the cameras, and they have the following specs:
model: 617-97073
volts: N/A
Watts:N/A
HZ: N/A
hahaha they keep secret everything.

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$!!
