[Elecraft] K3 Power

[Thom LaCosta]

The K3 FaQ states

What are the power supply requirements?

The K3 DC voltage required is 13.8 V nominal/recommended; 11 V recommended 
minimum; transmit disabled below 10 V; system shutdown below 9.0 V.

How many amps?
Is there a suggested supply?

If the rig is supplied with power pole connections, can one purchase the mating 
cable that would be used to connect the rig to the power supply?
