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

. Shafts u
p
to 3/4” diameter can be accommodated b
y
an accessory clamp.

. The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DR
