Hi,
I received one of those boards from the usual Chinese supplier. I tried
to power it up according to the specs but the DC/DC converter doesn't start.
Tracing the power path, I find that after protective diodes and fuses,
the -48 V line is interrupted by a power MOSFET and the question is: is
it necessary to make any other connections, such as strapping the
mounting holes to a chassis, in order to make it start? Or maybe is my
unit faulty?
TIA for your help,
Ignacio EB4APL
