changing between outlets of different voltages. The only thing which may need
adjustment on the charger is the big “Amps” knob on the front. Turn this knob up or
down depending on the amperage available from the outlet. With the “Amps” knob
in the most clockwise position a PFC-50 can draw up to 50 amps and a PFC-75 can
draw up to 75 amps.
EXAMPLE: A PFC-50 plugged into a standard 120V outlet at 15 amps would be
able to draw about 1,800 watts (120x15 = 1,800). The same PFC-50 plugged into a
240V outlet at 50 amps could draw about 12,000 watts, meaning a charge time that
is over six times faster than in the 120V scenario.
PFC-50 Input Wiring (For Front Input Corded Models)
For rear connection PFC-50 models refer to the PFC-75 input wiring section below.
Most PFC-50 chargers built before 2011 were shipped with a NEMA 14-50 on the
AC input cable. Please leave this attached and make adapter cords if you intend to
change what it plugs in to. The 14-50 outlet is very common at RV parks, in homes
for electric ovens and at some public charging stations.
To attach the PFC-50’s input cable to a common 110/120V three prong 5-15 or 5-20
plug purchase a 14-50 receptacle and make an adapter exactly as shown in figure
08. If you wish to make an adapter cord to connect your PFC-50’s input cable to a
220/240V three prong plug (like a NEMA 10-30, 10-40 or 6-50), use a 14-50
receptacle and simply disregard the white wire and the middle straight neutral prong.
Run the green wire to the ground prong and then the red and black wires to either of
the two hot prongs.
The front connection PFC-50 chargers come with a 4 wire AC input cable but do
not ever use the White neutral wire for anything. Even though there is a 4-wire
plug on the unit, the white wire should never be connected to anything.
PFC-75 Input Wiring
The PFC-75 is shipped with an 3 connector Anderson Power Pole array and 3 black
1 AWG cables for the AC input. The other ends of the included connector are to be
wired to an appropriate 75 amp or greater plug. Manzanita Micro recommends a 100
Amp pin and sleeve style plug. The male end is attached to these 3 input cables so
that it can plug into a female twistlock that is bringing the power from the wall.
NOTE: Extra Power Pole connectors can be purchased for making a second
“Power-Pole-to-male-NEMA-14-50” adapter. With this configuration the charger
must not be allowed to draw over 50 amps but it makes it easier to plug in at more
locations and still get a decent amount of current. The 14-50 outlet is very common
at RV parks, electric ovens and some public charging stations.
