or proportional modulation of dampers in HVAC systems. Actuator sizing should be
d

T
he actuator is mounted directly to a damper sha
f

o
f its universal clamp. A crank arm and several mounting brackets are available for
a
pplications where the actuator cannot be direct coupled to the damper shaft
.
T
he actuator operates in response to a 2 to 10 VDC, or with the addition of a
