In laymans terms you won't get 70 amps into your EV unless your 240 Vac
line is as stiff or Stiffer than our power bench. YOU won't get the
PFC50 # 2 to suck more than 50.7 amps. That's what I set it to. That
50.7 amps will be the same no matter what voltage is at the plug.
The output current will vary in current as the input voltage sags. And
yes my power bench sags to 234 volts at 50 amps of load. So it's
possible it your have a 50 amp source that doesn't sag below say 240 at
all to get even more amps of output. But please do not take the charger
above 250 VAC.
Some Watt Log numbers on the Hair Ball proto PFC50 Buck enhanced.
234 VAC 49.9 amps AC delivering 66.4 amps of 147.2 Volts DC
234 49.9 80 + 104 VDC Windloader limited. aka
I chickened
out!!!
And I have a 80 amp fuse in there!!!
So if you have 235 or more volts at a 50 amp draw, you will rail the
output amps at about 75 amps
