makes it very easy to adjust the big amps knob to safely get the maximum number
of amps out of whatever you're plugged into.
There is now also a new and improved Multifunction Meter available as an upgrade
for any PFC charger model (see figure 14 below). The new Multifunction Meter can
display input voltage, input current, total power being consumed (in kilowatts), and
the real-time Power Factor. Below the main display are 4 round LEDs which indicate
which function is being displayed. Press the blue "SEL" button momentarily to cycle
through which information is displayed. Holding the select button down will initiate a
cycling mode where the display will cycle through each display function
automatically.
This advanced meter provides very useful information for gauging power usage and
efficiency levels under various charging circumstances. It also gives users an idea of
how good the power source is that they are plugged into.
The Power Factor (PF) function provides an idea of system efficiency. Best case
would be a PF of 1.00. Manzanita Micro chargers will display a higher power factor
when they are running at full power. The PF rating also will tend to be at its best
when charging a battery pack which is greater than or equal to the AC input line
voltage.

Optional Rear Control Port For Current Control or SAE J1772
Since the end of 2012, Manzanita Micro PFC-20/30/40 series chargers have
included a new control port on the rear of the charger chassis.
This control port enables the charger's current level to be adjusted remotely either
