FM1803-2 Furlmatic Windcharger
System
Updated and more powerful!
Technical Features
The FM1803-2 Furlmatic Windcharger
with
its robust 3-bladed wind turbine is supplied with
it’s purpose designed controller.
x
New 3 bladed turbine design combines an
efficient profile with a durable injection
moulded construction.
x
The 3 phase generator has a very low
torque enabling power generation to start
from just 3m/s (<7mph) windspeed.
x
Rutland unique disc type brushless
generator design has a high degree of
inertia that keeps the turbine spinning
between gusts of wind where other
designs stop and start. As such the
FM1803-2 delivers more power into a
battery over a given period than all other
commercial turbines of the same diameter
that we know of and even some larger
turbines.
x
Sliprings at the tower top allow the
turbine freedom to find the wind over
360
q
rotation.
x
AC power is generated and transmitted to
the controller. As the AC is generated at
high voltage power losses are low
allowing small cable to be used,
minimising installation costs.
x
Marlec’s well established furling tail
system is used on the FM1803-2. The
tail normally directs the turbine into wind
but a simple gravity induced mechanism
operates at 15m/s (35mph) to push the
turbine off wind thus reducing it’s speed.
This provides protection from the forces
exerted on the turbine and tower in very
high winds and assures longevity of the
product.
x
MPC1 Controller incorporates 4 key
features; 3 phase transformer to reduce
voltage, a rectifier to convert AC to DC
an electronic controller and battery
overcharge protection.
MPC1 Controller
electronics optimise the
performance of the turbine to generate more
power into the battery. It does this by
switching the power ratios between high and
low wind speed modes. The digital display
keeps the user informed of the status of
operation. The MPC1 functions and
features are:
x
LCD displays: battery voltage,
charge in Watts & Amps and low
battery voltage warning sign.
x
LCD also displays the mode of
operation: low wind mode, high
wind mode, stall, battery full.
x
A switch to start and stall the
turbine.
x
LED’s to indicate operation modes
& warnings
x
Automatic delayed change of
operation to avoid rapid switching.
This takes account of short gusts of
wind and waits for a sustained higher
wind or voltage to be reached before
changeover.
x
Battery overcharge protection -
turbine stall is invoked when the
batteries are full at 14.4V & 28.8V
@ 25
q
C thus reducing unnecessary
wear and tear on the turbine. It
automatically restarts as the battery
volts fall to the lower limits of 12.5V
& 25V.
x
A re-set button allows the user to
restart the wind turbine before this
lower limit is reached.
x
Temperature compensation ensures
that the battery voltage switching
points are automatically adjusted for
ambient temperature to maintain
optimum battery performance
