General Description
The Vanner
VANN-Guard Battery Equalizer
is an efficient and highly reliable method of obtaining a 12
volt DC power source from a 24 volt DC electrical system. The equalizer makes the batteries look like
they are in series and parallel at the same time. In addition to providing regulated 12 volt power, the
system ensures that battery voltages remain equal which significantly extends battery life. The equalizer
is designed to save your batteries and the money you would spend replacing them. Users of the Vanner
battery equalizers know that it is the most cost effective and dependable solution for dual voltage
systems.
A typical system would include a 24VDC power source, such as an alternator, two 12 volt battery banks in
series, and the battery equalizer. The equalizer connects to the 24 volt, 12 volt and ground terminals of
the battery system. When the 12 volt loads require power, the equalizer ensures that the current is taken
equally from both batteries, and that the voltages of the two batteries are kept equal. This equalization
ensures extended battery life and provides a stable 12 volt supply for operating accessories.
Paralleling equalizers:
Vanner Battery Equalizers may be operated in parallel to provide more power.
NOTE:
The Vanner
VANN-Guard Battery Equalizer
is an extremely reliable device and, when installed
according to the instructions, will provide reliable operation for an indefinite period of time. However, if a
system abnormality should develop that would cause an equalizer malfunction, damage to the battery
system could result if 12 volt loads are present.
