Note 1 - Minimum torque is produced at minimum voltage, minimum temperature
Note 2 - Damper area is calculated using approximately 4 in-lb/sq.ft. of damper area. This is an average torque requirement for good quality dampers operating under a 1" WC pressure drop. Check damper specifications for exact torque requirements.
Note 3 - The on board microprocessor measures the actuator's full stroke on startup. It then adjusts the actuator speed to ensure 150 second run time for 35-95°. Below 35° stroke, the speed is constant and run time varies with rotation angle.
