Product Overview

Accessories/Repair Parts
Description and Application
These tri-state ControlSet Actuators are designed
to control small damp ers, 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 diam-
eter damper shaft, eliminating the need for expen-
sive 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 oating thermostat or building automation
system. Both minimum and maximum end stops are
stan dard to limit the rotation. A non-rotation bracket,
to prevent lateral movement, is included with each
actuator. A gear disengagement buon 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 eld installed.
Specifications and design subject to change without notice.
