VOLTAGE AND TEMPERATURE REMOTE SENSOR
(OPTION)
ADVANTAGES
The intern battery voltage varies according to ambient temperature. (30mV per degree).
To deliver the best voltage and avoid overloading or under loading of the battery UNIMPPT is originally
equipped with a temperature sensor integrated on regulator gear. With this, UNIMPPT measures the ambient
temperature to adj
ust charging voltage according to battery manufacturer’s recommendations. (30mV in 12V
and 60mV in 24V per °C under and over the reference temperature at 25°C).
However, when there is a temperature difference
between the regulator environment and the battery (ex.
regulator located in a technical room and battery stocked
in a block), it is recommended to use Unisensor remote
sensor. In this case, UNIMPPT will use as the temperature
reference, no the ambient temperature measured by the
regulator but the temperature measured by the remote
sensor.
UNISENSOR allows too to optimize voltage
measurement for more charge precision. Thanks,
Unisensor, the voltage measurement doesn’t do
that anymore at across the regulator, but directly
on the battery to avoid voltage drops cause by
wiring. In order to measure and control the charge
more precisely.
INSTALLATION AND CONNECTION
•
Fix the sensor thanks 2 bolts or double-sided
sticker to the nearest of the battery.
Warning: Do not theard it in the battery
•
Connect 2 measure wires on Unisensor.
and
•
Ensure that green light is correctly turned
on. If the yellow light is turned on, a polarity
reversal occare. Modify wiring until flash
green turn on.
•
Connect cable between the regulator and the
sensor.
