Linear Damper Actuator
for 2-position or 3-position
Damper Control
Description
Linear drive actuator used for controlling volume regulators for ceiling outlets and for
damper adjustment.
Features
• Forceforpullandpushof34lbs.
• Nominal voltage 24 Vac
• Controlled by a three-point output signal
• Positioning speed at 50 Hz = 0.98 in./min., at 60 Hz = 1.18 in./min.
Application
The linear drive actuator can be mounted on air-handling units and ceiling outlets. It is
used for the control of volume regulators and ceiling outlets in VAV systems and for
damper adjustment in induction units and mixing boxes.
Z/C... assembly kits are available for the various applications described.
Principle of
Operation
The actuator is suitable for use with controllers having a proportional three-point 24 Vac
output signal or for open/close control.
The stroke direction of the threaded spindle is determined by the terminal connections
on the motor.
