KMC MEP-1271 1273 Direct Coupled tri-State Failsafe ControlSet Actuator

Previous Page

Obsolete Use Mep-7200 Series

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, controlller, or building automation system. A minimum 100 in-lb. of torque is available over the 90 deg 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.
