Application

N/A For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft from 1/4” up to 5/8” in diameter by means of its universal clamp. Shafts up to 3/4” diameter can be accommodated by an accessory clamp.
The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500 O resistor, a 4 to 20 mA control input from an electronic controller or positioner.
A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications.
