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?
Estimates:
About 0.9 A receive (minimum, not counting enabled options), 3 A @ 10W,
20 A @ 100W. We'll refine these after further testing.
Is there a suggested supply?
Not yet, but I'd use a 4-6 amp supply for 10 W and 20-25A for 100 W. To
minimize noise, use a linear supply or a switcher. If you have control
over the voltage, set it to 13 to 13.8 V.
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?
The rig comes with a mating cable that has properly installed APP
connectors at one end. Note that APP (Anderson Power Pole) connectors
are quite rugged, and we've never seen a failure in any of our products
that use them.
