Typical Specification
Sprin
g
return control damper actuators shall be direct coupled type which require no
c
rank arm and linka
g
e and be capable of direct mountin
g
to a
j
ackshaft up to a 1.05”
diameter. The actuator must
p
rovide
p
ro
p
ortional dam
p
er control in res
p
onse to a 2 to
10 VDC or, with the addition of a 50
0
Ω
resistor, a 4 to 20 mA control in
p
ut from an
e
lectronic controller or positioner. The actuators must be desi
g
ned so that they may be
u
sed for either clockwise or counterclockwise fail-safe o
p
eration. Actuators shall use
a brushless D
C
motor controlled b
y
a micro
p
rocessor and be
p
rotected from overload
at all angles of rotation. Run time shall be constant, and independent of torque. A 2 to
10 VDC feedback signal shall be provided for position feedback. Actuators shall be
c
ULus A
pp
roved and have a 5
y
ear warrant
y
, and be manufactured under ISO 9001
International Qualit
y
Control Standards. Actuators shall be as manufactured b
