return control damper actuators shall be direct coupled type which require
no crank arm and linka

a micro
p
rocessor
and be protected from overload at all an
g
les of rotation. Run time shall be constant,
and independent of torque. A 2 to 10 VDC feedback si
g
nal shall be provided for position
feedback or master-slave a
pp
lications. If re
q
uired, one SPDT auxiliar
y
switch shall be
provided havin

the capability o

must be constructed to meet the requirements
f
or Double Insulation so an electrical
g
round is not required to meet a
g
ency listin
g
s. Actuators shall be cULus listed, have
a 5
y
ear warrant
y
, and be manufactured under ISO 9001 International Qualit
y
Control
Standards. Actuators shall be as manufactured b
