Our most popular commercial grade motor that mounts on almost any driveshaft to give powerful and quiet control. Takes 24vac or DC, since motor is internally a DC drive motor with microprocessor based circuitry that kills power when motor reaches end of travel-this motor never even gets warm to the touch.
5 year warranty.
*Motor is used on our popular "Super Duty" SD series of Round Dampers. Also used on our popular SD3085 Series of Rectangular Dampers.
*Can be adapted to almost any damper using a drive shaft.
*Uses a fraction of the power of spring return dampers.
* Unique internal circuitry allows "one output control" from any thermostat or single pole switch (no relays needed!), unlike almost any other power open/power close damper motor - you get the best of both worlds, ease of wiring like a spring return, reliability and energy efficiency of a power open, power close 3 wire damper.
* Uses a single pole, double throw switch with a center off, this motor can be stopped anywhere in its range and will hold position in the airstream for balancing applications
