I have a Lambda LFS-40-12 power supply that I want to use for my son's
toy railroad. His hobby transformer failed. I pulled this LFS-40-12
from old equipment.
Here's the catalog
http://www.lambdapower.com/ftp/catalog/lfs_fall92.pdf
I am having trouble getting 12V out of it. I think that terminals S+
and S- and power supply and R+ and R- are remote sensing terminals. I
thought that by shorting R+ to R- I would get voltage between S+ and
S-, but no such luck.
Any ideas? Is it bad? I checked some voltages, there is reliable 160V
DC right after the DC rectifier, on the inputs of big DC
capacitors. After that, it becomes kind of murky.
