[Elecraft] See My NEW K2 Power Supply in EC2 Enclosure!

Rick,

I think we have a first prototype for the KPS-100!

On their linear supplies, Astron has the output on the boards for the 
meters that go on the front, weither the supply has them mounted or 
not.  The current output is actually a voltage/low current output that is 
proportional to the current output of the supply.  The supply itself has to 
be aware of what it is outputing, so it can current limit itself.  I 
suspect the same thing may exist on the switchers, if the same folks worked 
on the design.  You may see an indication on the schematic for the supply 
near the output where a line goes back into itself.  Problem is, you have 
to have a meter that matches their scale on the metered PS to use it.  Or, 
feed it into a microprocessor, and then display it on the 
K2......Hey,  that might be a cool trick.  (Note to Wayne, Need USB or 
RS-422 interface for K3 for external devices........)

The meters you chose are SWEET!  Glad the gave you a shunt, and not shunted 
you.

Good work on the Power supply.
