Three Stage Charging

Three stage charging is often recommended by battery manufacturers
for allowing the fastest possible recharge time without loss of batteries'
electrolyte (gel or liquid) which may be caused by sustained charging at
higher voltages. This three-stage regimen, Bulk, Absorption and Float,
may contribute to longer battery life. Contact the battery manufacturer if
you have questions about the necessity of charging the batteries using
the three stage system.
Gel-Cell/Lead Acid Selector Switch
According to most battery manufacturers, the ideal charge regimen for
gel-cell and wet or flooded lead acid batteries differs somewhat. The ideal
charge/float regimen has been programmed into the PM charger board
for either sealed gel-cell or flooded lead acid batteries. With the charger
function board installed gel cell/lead acid battery selection may be made
with a slide switch mounted on the board.
Temperature Compensation (Sensor Installed on Model PM-12-45)
Because low battery temperature increases resistance to charging and
high battery temperature reduces impedance, requiring a lower charge
voltage, the ideal charging voltage will vary depending on the temperature
of the battery's environment when it is being charged. With the charger
function board installed, the installer may then also install an optional
remote temperature sensor. The remote sensor will signal the PM to fine
tune its output voltage so that it is properly matched to the temperature of
the battery/battery environment.
Equalize Timer Option
Some manufacturers of flooded lead-acid batteries recommend a charg-
ing process known as equalization for extended battery life. This process
involves occasionally charging a flooded lead-acid battery at a very high
voltage for a short period of time in order to completely de-sulfate each of
the battery plates, essentially equalizing their voltage. With the charger
function board installed, the installer may choose to wire in this option at
the time of installation.
B) DC Quick Connect Wiring Kit
Note: This option is available only for systems which incorporate the
NEWMAR Power Function Manager. For complete information on this
product, please contact the factory.
A DC wiring harness quick connect kit is available from NEWMAR which
simplifies parallel wiring installation of multiple Power Modules with the
Power Function Manager and facilitates "hot change-out" of modules for
repair or replacement.
The kit consists of two wiring harness; one for positive and negative
DC output wiring, another for alarm contact wiring. Wires are pre-cut to
proper length, all necessary connectors are installed and the bundles
are neatly tie-wrapped into proper position for a simple and professional
installation.
For more information, or to order the quick connect kit, please contact
the factory and specify the number of PM's (2-6) in the system being
installed. Model QCK-3: 1-3 PM's. Model QCK-6: 4-6 PM's.
C) AC Transient Suppressor
For communication sites which are subject to "dirty" AC voltage with line
transients or spikes, a commercially available AC transient suppressor
may be required.

The suppressor provides continuous bi-polar, bi-directional, non-inter-
rupting protection for both the PM and load from damaging high voltage
transients. It is installed in-line with AC input to the PM. Status indicators
verify input and "PROTECTED" conditions and alarm contacts indicate
when the unit has tripped and equipment is in the unprotected mode. Two
models are available for 115V and 230V applications. Contact the factory
for more information on how to obtain this transient suppressor.
