Need help from someone that knows PCB design and can work with a .lay file. I was given a pcb file (.lay file attached in zip) for a power supply and needed a transformer to tie on to it.

I have a 3FL16-350 Tamura datasheet is attached also that I was told would be an excellent choice.

I don't understand how to work in design so if anyone can give assistance to put the Tamura on this would be great.

Thanks in advance for any help.
Bob

Re: +/- 5V power supply.

Thank you so much. This will give me something to work on.
All I have to do is figure out how to get this on the PCB board.

Thanks again
Bob
 

Re: +/- 5V power supply.

On a second thought, :cool: there’ s a need to use a fusible unit in the primary circuit and maybe it’s better to rotate the LM7905 integrated circuit as this may require some small heat sinks.

Re: +/- 5V power supply.

Hi mister_rf,

Thank you for this.

Is there a chance you could put this in a .lay file? I have a couple small heat sinks so that's not a problem.

Thanks
Bob

I do have pictures of the unit I pulled this transformer out of if that will help. It's an Adtran DSU 56/64 1997 back during the 56K internet circuit days. It was mentioned just cutting the area out and use that but not knowing enough I didn't.

I do have another one of these that I haven't tore apart yet if the complete setup is needed.

Try adjusting this PCB for the correct transformer mounting footprint …

Re: +/- 5V power supply.

Ok thanks. I'll see what I can do. I'm not sure the viewer will let me do that but I'll find a way to work with it.

Thanks again
Bob
 

Re: +/- 5V power supply.

Hi,

I printed out your .lay file, you have the PCB footprint perfect for the holes.

Thanks
 

Re: +/- 5V power supply.

mister-rf, where you make the PCB layout (software) n how make it 3D,? I use Eagle software, please tell me how.
 

Re: +/- 5V power supply.

I just got all pieces to put this together.

It keeps blowing the fuse. Any suggestions were to look?

I have pins 1234 on the AC in.

Thanks
Bob

Re: +/- 5V power supply.

I have a question about part of this.

The datasheet for the 3FL16-350 Shows pin 1 & 3 together and 2 & 4 together.

But in the datasheet Pin 3 is the last one and pin 4 is the third one, as with the out put 5 & 7 are on the ends and pin 8 is the third one.

1 5
2 6
4 8
3 7

Could this be causing it to heat up and blow the fuse?

The datasheet is attached a couple entries above. If it's not there I can send it again.

Thanks.
Bob

Yes, now I have realised my mistake. Mea culpa... Reverse transformer pins 3 and 4, also pins 7 and 8 and later try to test the circuit by connecting series some light bulb (110v/40W-60W.

I'm glad to hear it wasn't all me.

Would you be able to send a new .LAY file? I only have the viewer/printer.

Thanks
Bob

mister_rf,

Thanks. Would you by chance have an updated .LAY file?, I'm only able to read them. Can't edit them.

Thanks
Bob
