PD 9180 needs 20 amp cord?
Hey all, With all this converter talk recently, I noticed that the prog. dyn. PD9180/9280 converter comes with a 20 amp cord and plug. Can't tell if the cord wire is 12awg but probably. Fine. So...

I figure a bit over 17 amps max on the power cord. This would be worst case, which I assume they have to design for.
14.4 volts * 80 amps = 1152 watts DC output
1152 watts DC / 80% efficiency = 1440 watts AC input
1440 watts AC input / 0.7 pf = 2057 VA
2057 VA / 120 volts = 17.14 amps
This is totally consistent with 1500 VA reported above for the 60 amp converter. (1500 VA * (80/60) = 2000 VA)
