NOTES
R = Resistive load.
L = Inductive load.
A = Ratio of RMS current to DC output current. Arm fuses are rated for this RMS current.
B = Ratio of peak device current to DC output current.
C = Ratio of secondary RMS line current from supply to DC output current. Line fuses are rated for this RMS current.
D = Ratio of no load RMS line to line voltage to no load DC voltage.
E = Ratio of RMS phase voltage to DC voltage.
F = Ratio of peak phase voltage to DC voltage.
