Low friction screw drive (linear actuator) rated for -5
ºF to +160 ºF (-28 ºC to +71 ºC).
Powered by a 12 V motor with integral case hardened steel
gear reducer. Motor speed reduced to 260 rpm. Generates
520 inch lb. of torque at 12 V.
Maximum opening arc of 110º. Approximate opening time
(90º): 18 seconds, depending on weight of gate.
The system is powered by a 12 Vdc automotive or marine
Battery charge is maintained by a 120 Vac, 18 Vac output
transformer [rectified to 14.5 Vdc (40 VA) through the
GTO control board] or by optional GTO Solar Panels [the panel
should generate minimum of 5 W at 300 mA]. A
diode on the control board prevents battery discharge.
IMPORTANT: Never use both transformer and solar panel - this will
damage the battery and control board.
One (1) blade-style control board fuse is rated for 15
NOTE: The transformer should not be directly connected to any
battery. Do not replace fuses
with higher ampere rated fuses; doing so will void your warranty
and may damage your control board.
GTO microprocessor-based control board is set for single
leaf, pull-to-open gate installations. DIP switches can be
adjusted to accommodate an optional kit for push-to-open gates
(see Accessory Catalog).
Control board has temperature compensated circuits.
A circuit on the control board regulates charging. "Sleep
draw" is 25 mA; "active draw" is 2 to 5 A.
Auto-memorization of digital transmitter code.
GTO remote-mounted RF receiver tuned to 318 MHz.
Opener length with push-pull tube fully retracted is 371/4",
mounting point to mounting point.
Adjustable auto-close timer (OFF to 120 s), and obstruction
Power terminal bock accommodates a transformer or solar
DIP switches simplify setup of gate opener.
Accessory terminal block fully compatible with all Mighty
Mule access controls.
Control board allows connection of safety edge sensors
and photoelectric sensors.
Audio entrapment alarm sounds if unit encounters an obstruction
twice while opening or closing.
The Gate Capacity Chart shows approximate cycles, per day,
you can expect from the Mighty Mule 350 Automatic
Gate Opener when powered with a transformer. Actual cycles may
vary slightly depending upon the type and condition
of gate and installation.
