PFC-20/30/40 SERIES
BATTERY CHARGER
MANUAL REV 3.1
General Overview
The Manzanita Micro PFC chargers are a unique group of powerful, efficient battery
chargers. The chargers will operate on any voltage from 100 up to 240 volts AC.
The chargers can be set to run automatically when plugged in, yet they also have far
more user adjustable functions than other electric vehicle chargers. Every model is
user adjustable to charge batteries from 12 to 450 Volts DC. All the chargers are
power factor corrected and are available with enhanced options such as AC input
power displays. With so much flexibility and models from 20 to 75amps, your PFC
charger may be the last charger you ever need to buy.
Speed and Efficiency
The essential ingredient for fast recharge times is to deliver as much power to the
battery as practical. The key to polite opportunity charging is to be able to share
outlets with other equipment and make efficient use of limited current. The
Manzanita Micro PFC line of chargers has an adjustable current throttle knob to
allow the chargers to be turned down to operate on very limited power sources.
Efficiency is usually well over 90% and power factor is typically better than 0.9.
What does the PFC mean?
PFC stands for Power Factor Corrected. The Manzanita Micro PFC chargers have
special circuitry to make sure the voltage and current are drawn in unity, so that the
apparent power (Volt-amps) is very close to the real power (Watts). This ratio of
apparent power to real power is the power factor and it is expressed as a number
