The PFC-75 is the same size footprint as the PFC-50 but includes a panel mounted line current meter. Extra heavy duty wiring and components designed for running at 75 amps continuously, 75 amps in to 75 amps out The PFC75 weighs 42 pounds in a box that is 19.5" x 10.5" x 6.5"

The (Power Corretion Factor) PFC line or battery chargers are Extremely versatile.
designed to charge any battery pack from 12 volts to 360
volts nominal (14.4 to 400 peak.) power factor corrected and designed to either put out 20 amps (if the battery voltage is lower than the input voltage) or draw 20 amps from the line (if the line voltage is lower than the battery voltage.) The charger will operate from any voltage from 60 to 250 volts AC at either 50 or 60 Hz. The charger has a throttle knob to allow the user to turn the current down when using shared or undersized circuits. This charger is designed to operate at full capacity from a 30 Amp circuit. Efficiency is 88% to 96% percent on the beta test units depending on input and output voltage.
Safety circuits:The charger is protected from reverse polarity installation by an internal fuse.Over temperature conditions cause the current to ramp back to prevent the internal temperature from going over 160F (more air makes more power.) The charger is programmed to be a constant current source and will survive a short circuit indefinately.There is a programmable timer to shut off the charger after a user selectable period.The charger is BatReg aware (turns down or off if a BatReg gets hot.)This charger is non-isolated. The negative terminal of the battery is connected to the negative terminal of a rectifier bridge with the AC terminals connected to the incoming line. The PFC20 weighs 16 pounds and resides in a box that is 13 x 9 x 5 inches.The PFC50 weighs 42 pounds and resides in a box that is: 19.5 x 10.5 x 6.5 inches.The essential ingredient for fast recharge times is to deliver high power to the battery. The key to polite opportunity charging is to be able to share outlets with other equipment and make efficient use of limited current. The PFC line of chargers have a throttle to allow the chargers to be turned down to operate on very limited power sources such as small generators. The PFC20 has demonstrated putting 2200 watts into a 156 volt battery pack from a 2400 watt generator. Efficiency and power factor are both better than 0.9. The PFC20 can put 5 kW into a 360 volt battery pack from 240 VAC input or 2500 watts into a 180 volt battery pack from 120 VAC. The PFC20 does this while operating from a 20 amp circuit breaker The charger output can be adjusted for any pack voltage from 12 volts
to 360 volts with the twist of a 20 turn trimmer pot. There is no need to
buy different chargers for the different electric vehicles you may need to
charge. The charger can be reprogrammed to another pack voltage if you
change the number of batteries in your system. There is no longer a need to
buy another charger everytime you add or take batteries out of your system.
Our EV chargers are designed to be as versatile and as powerful as possible
within the limits of residential power infrastructure.

The PFC20 weighs 16 pounds and resides in a box that is 13 x 9 x 5.5 inches.
The PFC30 weighs 17 pounds and resides in a box that is 13 x 9 x 5.5 inches.
The PFC50 weighs 42 pounds and resides in a box that is 19.5 x 10.5 x 6.5 inches.
