Non-spring return electronic damper actuators
Electronic rotary non-spring return damper actuators use a patented self-centering shaft adapter, which concentrically holds the damper shaft with no slipping, and the lower torque actuators use a single point centered connection. Many of the actuators offer selectable modulating signals of either 0-10VDC or 2-10VDC. Enhanced models offer longer cycle ratings for increased performance.
