Shown here are the transfer characteristics curves that show the output power level versus the applied analog input for all the selectable modes. The 0-to-100% of the Phase Angle Control curve is made up of more than 1800 discrete steps, essentially producing a very smooth curve. As for the burst fire curve, since it works for full AC cycles and is based on a 20 cycle period, there are 20 discrete steps with the burst mode. Therefore, the resolution of 0-to-100 is in 5% increments.
