Technical Specifications

Mighty Mule® 500 E-Z Gate Opener
DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF
to +160 ºF (-20 ºC to +71 ºC). Use of heater bands on arm
and control box will enhance performance in extreme cold
temperatures.
• Powered by a 12 V motor with integral case hardened steel
gear reducer. Motor speed reduced to 260 rpm. Generates
680 ft. lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time
(90º): 20 seconds, depending on weight of gate.
POWER
• The system is powered by a 12 Vdc, 7.0 Ah, sealed,
rechargeable acid battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output
transformer rectified to 14.5 Vdc (40 VA) through the GTO
control board. Blade-style control board 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.
• OPTIONAL: Battery charge is maintained by GTO Solar
Panel Charger: float voltage of 14.5 Vdc output from a
10-7/8" x 10-1/2"solar panel. Generates minimum of 5 W
at 300 mA. A gated diode on the control board prevents
battery discharge.
NOTE: "NR" indicates this size
and weight combination is not
recommended for the
Mighty Mule® 500.
NOTE: Ball bearing hinges
should be used on all gates
weighing over 250 lb.
To determine the number of cycles the gate operator will perform using solar panels, please see the specifications
listed on page 23 or call (800) 543-1236 or (850) 575-4144 for more information.

* An operation cycle is one full opening and closing of the gate.
These specifications are subject to change without notice.
• 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.
• Operator length with push-pull tube fully retracted is
40-1/4" mounting point to mounting point. Max stroke 22".
• Adjustable auto-close timer (15 to 120 s), and obstruction
sensitivity.
• Power terminal block accommodates a transformer or solar
panels. NOTE: Do not use solar panel and transformer
at the same time.
• DIP switches simplify setup of gate operator.
• Accessory terminal block fully compatible with push
button controls, digital keypads, safety loops, etc.
• 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.
OPERATIONAL CAPACITY
• The Gate Capacity Chart shows approximate cycles, per
day, you can expect from the Mighty Mule® 500 Automat-
ic Gate Operator when powered with a transformer. Actual
cycles may vary slightly depending upon the type and
condition of gate and installation.
