Technical Specifications

MIGHTY MULE 571W/572W GATE OPENER

• Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-20 ºC to +71 ºC).
• Opener length with push-pull tube fully retracted is 40.25", mounting point to mounting point. Maximum stroke is 20".
• Maximum opening arc of 110º. Approximate opening time (90º): 14 seconds, depending on weight of gate.
• The system is powered by a 12 Vdc battery (included). Optional automotive or marine battery may be used (not included).
• Battery charge is maintained by Mighty Mule transformer or optional Mighty Mule Solar Panels.
• The system uses 25 A Mini ATC blade-style fuses.
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.
• Adjustable auto-close timer (OFF, 3 to 120 seconds), and Dual Sense Technology Entrapment Protection.
• Accessory terminal block fully compatible with all Mighty Mule access controls.
• Audio entrapment alarm sounds if unit encounters an obstruction twice while opening or closing.

Before You Begin

POWERING OPTIONS
1. Determine Charging Option for Battery: Transformer OR Solar
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT
THE SAME TIME. It will damage the control board.
IMPORTANT:
● 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.
* If the gate operator controller is OFF, the system will NOT charge the battery.

the maximum number
of gate cycles to expect
per day in a particular
area when using from
* Power increments are for reference only.
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.
