MIGHTY MULE HD272 DUAL GATE OPENER
_____________________________________
DRIVE
_____________________________________
• 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 gear reducer. Motor speed reduced to 280 rpm at 12 V.
• Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.
_____________________________________ POWER _____________________________________
• The system is powered by a 12 Vdc automotive, lawn tractor or marine battery (required but not included).
• Battery charger is on the control board and is maintained by 120VAC to 16VDC output transformer or by optional
Solar Panels; the solar panels should generate minimum of 10 Watts (600 mA). A diode on the control board prevents
battery discharge.
IMPORTANT:
Never use
both
transformer and solar panel (20 Watt Max.) — this will damage the battery and
control board.
• Two (2) Mini blade-style fuses are rated for 15A.
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 is set for dual leaf, pull-to-open gate installations. Jumper can be removed to
accommodate an optional kit for push-to-open gates.
• Control board has temperature compensated circuits. Learn based digital transmitter technology provides millions of
codes for enhanced security.
• RF receiver tuned to 318 MHz.
• Opener length with push-pull tube fully retracted is 26 3/8", mounting point to mounting point. Maximum stroke is 13".
• Adjustable auto-close timer (OFF to 3–120 seconds), and Dual Sense Technology™ stall force.
• Power terminal block accommodates an included transformer or optional 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.
_____________________________________ OPERATIONAL CAPACITY _____________________________________
• Maximum gate size: 300 lbs., 12' long.
NOTE: BALL BEARING HINGES SHOULD BE USED ON ALL GATES WEIGHING OVER 250 LB.
