Functional Description
POWERplus User Guide 1.1.0 8 350-00104-4
When the battery nears the float stage voltage the charger transitions to a constant voltage mode. Float
charging continues at this voltage and is automatically terminated after a period of time. The charge cycle
is repeated when the battery voltage falls to the lower edge of the float cycle.
If the charger establishes that the battery is below the fully depleted discharge level it will enter the pre-
conditioning phase and trickle charge the battery. If the battery voltage rises sufficiently the charger will
switch to the normal charge cycle, but will automatically terminate if the voltage does not rise to the
required level.
Other battery types
The charge requirements for other battery types may differ from the types supported by POWERplus. Do
not use the charger with battery types such as Lithium Polymer batteries which have markedly different
charging parameters.
Charge Indicator
A front panel LED shows which phase of the charge cycle the charger is in. The LED is displayed as RED,
GREEN or AMBER (RED/GREEN) but the meaning of the indicators is different depending upon whether
you are charging a Lead-Acid or LiFePO4 battery type.
LEAD-ACID BATTERY
When a LiFePO4 battery is in the charge mode, the color of the LED is green. It is illuminated when the
battery is being charged and extinguished when the battery is not charging, is in the float charge mode or
the charger has been disabled.
USB Charging
POWERplus provides two USB charge ports. These ports automatically detect the type of device
connected and can each charge up to 1.5A (depending upon the device connected). Current limiting to
prevent overload is provided.
