Technical Specifications

_____________________________________
• Low friction screw drive (linear actuator) rated for -5 °F to +160 °F (-20 °C to +71 °C).
• Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm.
• Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.
_____________________________________
• The system is powered by a 12 Vdc automotive or marine battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output transformer (40 VA) through the GTO control board or
by optional GTO Solar Panels; the panel should generate minimum of 5 Watts at 300 mA. IMPORTANT: Never
use both transformer and solar panel— this will damage the battery and control board.
• One (1) blade-style fuse is rated for 15 A.
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 DIP switches are set for single leaf, pull-to-open gate installations. DIP switches can be adjusted to
accommodate push-to-open gates.
• 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 RF Receiver tuned to 318 MHz.
• Opener length with push-pull tube fully retracted is 37
is 19".
• Adjustable auto-close timer (OFF to 3–120 seconds), and obstruction sensitivity (stall force).
• Power terminal block accommodates a transformer or solar panels.
• 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 Gate Opener
when powered with a transformer. Actual cycles may vary slightly depending upon the type and condition of gate
and installation.
An operation cycle is
one full opening and
closing of the gate.
NOTE: BALL BEARING HINGES SHOULD BE USED ON ALL GATES WEIGHING OVER 250 LBS.
To determine the number of cycles the gate opener will perform using solar panels, please see the
specifications listed on page 8.
