The 12V accessory jack on the K3 was upgraded from .5A to 1A for the addition of the SVGA option on the P3. This was before the KAT500 was available. The P3 draws .5A without the SVGA option and draws .7A with the SVGA option. The KAT500 draws 1A max with a specification of .2A typical. If you don't have a P3 it is probably OK to use the K3 12V accessory jack for the KAT500. If you do have a P3 with or without the SVGA option I don't think it would be a good idea to run the KAT500 power from the K3. I have a P3 with the SVGA option and run it from the K3. When I had a KAT500 I ran it from the shack 12V power supply that powered all the shack 12V accessories. Alternatively, you could run it directly from the power supply for the K3.
