ADJUSTING REGULATION VOLTAGE
The voltage regulaon set point is adjustable using the potenometer on the
side of the AIR turbine body.
To accurately set the regulaon voltage, disconnect the turbine from the
baeries and use an adjustable voltage source (i.e. power supply) and or mul
-meter to apply the desired voltage across the posive and negave turbine
leads. With the target voltage applied, turn the potenometer fully clockwise,
then slowly turn it counter-clockwise unl the LED just illuminates. The regu-
laon set point is now xed to the voltage applied across the turbine leads.
A second method is to turn the potenometer fully clockwise. Then monitor
baery voltage while charging and when the desired baery threshold level is
reached, disconnect all current sources (other than the wind turbine) and
loads. This may take a few aempts so that the desired voltage equals the
resng baery voltage. Slowly turn the potenometer counter clockwise un-
l the LED begins blinking.
Alternavely, the regulaon set point voltage may be adjusted using a trial
and error method. Use the accompanying chart as a guide to increase or de-
crease the voltage regulaon set point. Monitor the baery voltage over a
period of me and make small adjustments unl the regulaon set point volt-
age is at the desired level.
* Adjustment ranges are approximate; actual ranges may be greater.
** Turn clockwise to increase voltage, counter-clockwise to decrease voltage.
USING AN ALTERNATE CHARGE CONTROLLER
There are some condions under which the AIR wind turbine’s internal regu-
lator is not opmal as the primary regulator and instead an external diver-
sion load controller can be substuted. These condions include:
• Systems where baery temperature varies widely: Baery charge e-
ciency varies in extreme temperatures. If these condions exist, use an
external regulator with a temperature compensaon sensor to opmize
the charge rate.
• Baeries that are extremely sensive to charge voltage: Follow the rec-
ommendaons of the baery manufacturer. For most baeries the tur-
bine’s internal voltage regulator is adequate. However, the most con-
servave approach is the use of a diversion load controller due to 3 stage
charging.
• Mulple turbine installaons with a bus system will typically funcon
best using a single voltage regulator (i.e. diversion load controller) close
to the baery bank. This is parcularly true if the wire lengths connecng
each turbine to the bus vary by distance or wire gauge. Without a diver-
sion load controller, mulple turbines may shi into baery regulaon at
slightly dierent mes due to line loss dierences, etc.
CAUTION: Increasing the voltage regulaon set point above the ini-
al factory seng will NOT increase the power output of the AIR wind
turbine. This adjustment changes the voltage at which the turbine
stops charging the baeries. By set-ng the voltage too high you may
increase the probability of overcharging and damaging the baeries.
