Supplemental Instructions
IMPORTANT PRECAUTIONS
Follow the battery manufacturer’s recommendations when selecting a battery for use with
this unit. The battery should be able to accept the full rated output current of this unit or
the battery may be damaged if the load is disconnected with the battery in a discharged
condition.
When using a load which is greater that the maximum continuous load specification, the
battery may not charge and may begin to discharge. The use of a low voltage disconnect
(LVD) is recommended.
Temperature compensation is disabled for parallel charger models. If using the charger in
an ambient temperature above 35 °C (95 °F) or below 15 °C (59 °F), contact our sales
department about receiving a custom model calibrated to match your battery and ambient
temperature requirements exactly.
INTRODUCTION
This unit is a Parallel Charger version of the model HPX30 Battery Charger. It is
designed to simultaneously float charge a battery while supporting or supplementing a
parallel load. It may also be used to maintain larger capacity batteries than it would
normally be able to charge.
OPERATING INSTRUCTIONS
Refer to the instructions in the main manual for connecting the battery. Connect the load
in parallel with the battery and charger (note the correct polarity if required by the load).
There is one indicator on the front panel. It will light yellow when the unit is operating in
the constant current mode at about 75% or more of its maximum rated current. In the
constant current mode the unit is not regulating voltage and the battery may not maintain
its charge. This unit should not operate continuously in the constant current mode. This
unit should only go into the constant current mode intermittently as the parallel load
requires, or when charging a discharged battery. The indicator light will switch from
yellow to green when the unit is operating in the constant voltage mode at about 75%, or
