Technical Specifications:

  • Low friction screw drive (linear actuator) rated for -5 F (-28 C) to +160F (+71C)
  • Powered by reliable 12 volt DC motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm. Generates 520 inch lb. of torque at 12V.
  • Maximum opening arc of 110.
  • Approximate opening time (90) is 18 seconds, depending on weight of gate.
  • The Silver-MD-Single system is powered by two 12 volt batteries (included). A weatherproof battery box is supplied to house the batteries.
  • Battery charge maintained by a 120VAC, 18VAC output transformer (rectified to 14.5VDC (40VA) through the control board or by optional GTO solar panels (the panel should generate minimum of 5W at 300mA). A diode on the control board prevents battery discharge.
    IMPORTANT: Never use both transformer and solar panel - this will damage the battery and control board.
  • One (1) blade-style control board fuse is 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.
  • 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 (FM148).
  • Control board has temperature compensated circuits.
  • A circuit on the control board regulates charging. "Sleep draw is 25mA; "active draw" is 2 to 5A.
  • Auto-memorization of digital transmitter code.
  • GTO remote-mounted RF receiver tuned at 318 MHz.
  • Opener length with push-pull tube fully retracted is 37-1/4", mounting point to mounting point.
  • Adjustable auto-close timer (OFF to 120 seconds), and obstruction sensitivity.
  • Power terminal block accommodates a transformer or solar panels
  • DIP switches simplify setup of gate opener.
  • 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.
  • Battery Heater recommended for zones where temperatures drop below freezing for extended periods of time to prevent cold weather discharge.
  • Operator arm
  • AC transformer
  • Control board (enclosed in weatherproof operator housing)
