Typical Specification
P
roportional control damper actuators shall be electronic direct-coupled type,
which require no crank arm and linka
g
e and be capable o
f
direct mountin
g
to a
shaft from 1/4” to 5/8”. Shafts u
p
to 3/4” diameter can be accommodate with an
accessory clamp. Actuators must provide proportional damper control in response
to a 2 to 10 VD
C
or, with the addition of a 500
Ω
res
i
stor, a 4 to 20 m

from an electronic controller or positioner. Actuators shall have brushless DC motor
technolo
g
y and be protected from overload at all an
g
les of rotation. Actuators shall
have reversin
g
switch and manual override on the cover. I
f
required, actuator will be
provided with screw terminal strip for electrical connections
(
LMB24-SR-T
)
. Run time
shall be constant and independent of torque. A 2 to 10 VD
C
feedback signal shall be
provided
f
or position indication. Actuators shall be cULus listed, have a 5-year war-
rant
y
, and be manufactured under ISO 9001 International Qualit
