Actuator Outputs

Electrical:

Position Signals, Internal feedback circuitry provides positive positioning of the damper

in relation to the controller signal.

Startpoint Adjustment, Adjustable potentiometer provides manual adjustment of the

actuator startpoint.

Mechanical:

Stroke,

Damper Approximately 2" (51 mm) from fully retracted to fully extended (includes

AM-601 linkage).

Valve Approximately 9/16" (14.3 mm) from fully retracted to fully extended.

Nominal Damper Area, Actuator sizing should be done in accordance with damper

manufacturer’s specifications.

Output Torque Rating, The proportional output torque rating of 15 lb-in. (1.7 N-m) is

available throughout the entire stroke and is based on the lowest force available under

normal operation, the spring return stroke, or at minimum (-10%) supply voltage.
