If a charger has a fixed output voltage which is ideal at, say 72° F, that same output may
cause a battery charged in a consistently high temperature environment to be overcharged,
resulting in excessive loss of electrolyte. Conversely, if the batteries are in a consistently cool
environment, they may be chronically undercharged, resulting in sulfation of the battery
plates. Either of these two conditions will shorten battery life.
Therefore, the Phase Three charger is designed to utilize an optional remote sensor (available
from NEWMAR; model TCS-12/24) which provides automatic temperature compensation.
The remote sensor will signal the charger to fine tune its output voltage so that it is properly
matched to the temperature of the battery/battery environment. The adjustment rate is
approximately -5 mV per cell per °C. (Note: The temperature compensation option is strongly
recommended for sealed, valve-regulated, AGM or gel-cell batteries.)
The remote sensor is provided with 30' of cable. One end of the cable is plugged into the
temperature compensation jack which is located on the right side of the charger. (See FIG-
URE 7.) The location of temp sensor jack is identified on the front panel.
If additional cable length is required, additional cable is commonly available from most
electronics supply retailers such as Radio Shack/Tandy. Request a 6 conductor modular-to-
modular line cord (part number 279-422, 25 feet long) and 6 pin modular in-line non-revers-
ing coupler (279-423).
The sensor itself should be mounted on the inside of the battery box, or more ideally,
mounted onto one of the batteries using a clamp or a small amount of silicon-type adhesive.
The sensor has a hole in the center which will accommodate a # 6 screw. If you have access
to the exterior of a wall of the battery box, you may drill a hole in the wall of the box and run
the screw through to mount the sensor onto the interior wall. Use caution when drilling so
that you do not accidentally puncture the case of any battery inside the box.
Important note: When wiring multiple chargers in parallel (see section E) and using
the temperature compensation option, you must use a separate sensor for each
charger, and the sensors must be mounted close together in the same battery box or
on the same battery for proper operation.
