[Elecraft] P3SVGA

[Paul Saffren N6HZ]

Hi Mike, 

The 12 DC input to the P3 is connected internally to two DC/DC converters. 
These both have over current protection and limit at less than 1/2 amp each. 
Probably worst case is 1 amp.  Of course if the cable itself shorts out or
the regulators somehow short at their inputs we would exceed that. 
Certainly putting an external fuse inline with the P3 power supply wouldn't
hurt. 

73, 

Paul
