Not really. I totaled the current draw of all the relays when pulled, added the microcontroller current and it was a tad over an amp.

I wonder if this "Do not take this power from the K3’s 12 VDC output connector, even if it has been upgraded for 1 Ampere" is because, at one time, the KAT500 had to be powered on before the K3 was powered on?
