Technical Specifications

1.  Determine Charging Option for Battery: Transformer OR Solar

IMPORTANT:

 

 

● The Mighty Mule gate operator is designed and intended for use with a 12 Volt automotive or marine type 

battery. The battery must be placed inside a weatherproof case and located within 6 feet from the Control Box. 

The 8 foot harness supplied connects the battery to the Control Box. 

 

● The transformer is designed for indoor use. If the transformer can be plugged only into an outside electrical 

outlet, a weatherproof cover/housing (available at local electrical supply stores) must be used. 

 

● If your gate is more than 1000 ft. from an AC power source, you will need to use at least 10 watt solar 

charging power to charge the battery [FM123]. Refer to the Solar Panel and Gate Activity chart below.

 

● All low voltage wire used with the Mighty Mule gate operator must be 16 gauge dual conductor, stranded, 

direct burial wire [RB509]. Do not run more than 1000 ft. of wire. 

NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT  

THE SAME TIME. It will damage the control board.

The table and map 

illustrate the maximum 

number of gate cycles 

to expect per day in a 

particular area when 

using from 10 to 30 

watts of solar charging 

power prior to the battery depleting to a state 

where the unit will not function. The figures 

shown are for winter (minimum sunlight). 

Accessories connected to your system will 

draw additional power from the battery.

Deep cycle marine battery is recommended 

for solar and/or high traffic applications.

DRIVE

•  Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-20 ºC to +71 ºC). 
•  Powered by a 12 V motor with integral gear reducer. Motor speed reduced to 260 rpm.
•  Maximum opening arc of 110º. Approximate opening time (90º): 18 seconds, depending on weight of gate.

POWER

•  The system is powered by a 12 Vdc automotive or marine battery. 
•  Battery charge is maintained by Mighty Mule transformer or optional Mighty Mule Solar Panels. 
• 

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.

CONTROL

•  Microprocessor-based control board for single leaf, pull-to-open gate installations.
•  A circuit on the control board regulates charging. "Sleep draw" is 15 mA; "active draw" is 2 to 5 A.
•  Auto-memorization of digital transmitter code. 
•  RF receiver tuned to 318 MHz. 
•  Opener length with push-pull tube fully retracted is 26

", mounting point to mounting point. Maximum stroke is 13".

•  Adjustable auto-close timer (OFF, 3 to 120 seconds), and Dual Sense Technology 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 edge sensors and photoelectric sensors.
•  Audio entrapment alarm sounds if unit encounters an obstruction twice while opening or closing.
