Direct-Coupled Tri-State ControlSet Actuator, 300 Sec/90° (50 in-lb)

Direct-Coupled Tri-State ControlSet Actuator, 300 Sec/90° (50 in-lb)

These tri-state ControlSet Actuators are designed to control small dampers, such as air terminal unit dampers. The MEP-5061 is an 18°/minute actuator, and the MEP-5071 is a 60°/minute actuator. A minimum of 50 in-lb. of torque over the maximum angular rotation of 95° is provided.

The actuator mounts to a 1/2-inch or 3/8-inch diameter damper shaft, eliminating the need for expensive and complicated linkages. When mounting to a 3/8-inch diameter shaft, the HFO-0011 shaft adaptor is required and must be ordered separately.

These bidirectional motors may be controlled via an SPDT floating thermostat or building automation system. Both minimum and maximum end stops are standard to limit the rotation. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement button allows manual positioning of the damper and/or gear train without energizing the actuator.

The actuators are protected against overloading. An optional feedback potentiometer and/or a (single or double) auxiliary switch can be field installed.

Features:

• Direct mounting to standard shaft sizes
• Available in 18° and 60° per minute models
• Bi-directional motors can be controlled by an SPDT floating thermostat or a building automation system
• Adjustable end stops
• Gear disengagement button for manual positioning
