FET stand for Field Effect Transistor. More accurately the Victors use Power MOSFETs or Metal Oxide Semiconductor Field Effect Transistors. The nature of these little beasties is a micro amount of drive current, fast on and off times, very low "on" resistance and the ability to leap tall buildings in a single bound! Effectively they act like a bidirectional switch that is controlled by voltage and can deliver 64 amps at less than .012 ohms between two current carrying pins. (i.e. source to drain resistance) So with three FETs in parallel for each leg, the entire package drops as much voltage as 4 feet of #10 wire (that's two conductors, one red and one black)
