The
KMC MEP-1272 ControlSet actuator is designed to regulate large control air
dampers and valves in HVAC systems. It is controlled by a 2 to 10 VDC signal (4
to 20 mA with 500 ohm resistor) from a thermostat, controller, or building
automation system. A 1 to 5 VDC feedback voltage output, which is
proportional to the control signal, is provided. The actuator mounts directly to
3/8” up to 3/4” diameter, or 5/16” up to 9/16” square, shafts eliminating the
need for expensive and complicated linkage. A minimum 100 in-lb. of torque is
available over the 90° angular rotation. A gear disengagement feature allows
positioning of the damper and/ or gear train without power. Protected against
overloading, the actuator does not require end or limit switches. The fail safe
feature allows selection of the return direction and a delay allows a full
charge before normal operation resumes.
