The
KMC MEP-7061/7063/7761/7763 fail-safe ControlSet Actuators are designed to
regulate large control air dampers and valves in HVAC systems. The 7061 and 7761
have 3-wire floating control signal inputs, and the 7063 and 7763 have 3-wire
floating control signal inputs with an added feedback potentiometer output.
These actuators mount directly to 3/8” up to 1.05” round or 5/16” up to 5/8”
square shafts, eliminating the need for expensive and complicated linkage. The
bidirectional motors may be controlled via a SPDT floating thermostat,
controller, or building automation system. A minimum 150 in-lb of torque is
available on the 7060 series and a minimum 300 in-lb of torque is available on
the 7760 series over the 94° angular rotation. A gear disengagement feature
allows positioning of the damper and/or gear train without energizing the
actuator. The actuators are protected against overloading and do not require end
or limit switches.
The
fail-safe feature allows selection for the direction of return, and a delay
allows a full charge before normal operation is resumed.
