KMC MEP-1271, 1273 Direct Coupled, tri-State, Failsafe ControlSet Actuator
The
KMC MEP-1271, 1273 ControlSet actuators are designed to regulate large control
air dampers and valves in HVAC systems. The MEP-1271 is a standard tri-state
controlled actuator while the MEP-1273 has an added feedback potentiometer. The
actuator mounts directly to 3/8” up to 3/4” diameter, or 5/16” up to 9/16”
square, shaft eliminating the need for expensive and complicated linkages. The
bi-directional motors may be controlled via an SPDT floating thermostat,
controller, or building automation system. 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. The actuator is
protected against overloading and does not require end or limit switches. The
fail-safe feature allows selection of a return direction and a delay allows a
full charge before normal operation resumes.
