Feature

Function

Benefit

Self-centering shaft coupling

Guarantees concentric fixation of actuator output coupling to damper shaft

Simplifies installation and eliminates damaging loads from high torque on damper shaft and actuator bearings

Brushless motor technology

Quiet, low power operation; proven reliable technology

Lower energy costs and eliminates occupant complaints regarding noise

Continuously engaged mechanical spring return

Returns damper to fail-safe position in response to power failure

Provides highly reliable fail-safe positioning compared to other types of actuators using an auxiliary spring winding motor

All metal housing

Protects gear train and control electronics

Provides outstanding durability in the toughest environments

Load independent

Maintains constant stroke time over all rated load and temperature conditions

Consistent control loop performance for all rated load and temperature conditions

Stall protection

Actuator responds to blockage in damper

Motor is protected ensuring long actuator life and long equipment life

Manual override

Allows unpowered positioning of shaft coupling

Simplifies installation, start-up, and troubleshooting

Highly visible position indicator

Shows orientation of damper blades

Facilitates setup, checkout, and troubleshooting

Wide temperature operating range

Rated for operation from -25 °F to 130 °F

Withstands environments that other actuators cannot
