AF120 US, AF230 US Typical Specification
On-off spring return damper actuators shall be direct coupled
type which require no crankarm and linkage and be capable of
direct mounting to a jackshaft up to a 1.05” diameter. The
actuators must be designed so that they may be used for
either clockwise or counterclockwise fail-safe operation.
Actuators shall have a manual positioning mechanism acces-
sible on its cover. Actuators shall use a brushless DC motor
and be protected from overload at all angles of rotation. Run
time shall be constant and independent of torque. If required,
2 SPDT auxiliary switches shall be provided with one switch
having the capability of being adjustable. Actuators must be
constructed to meet the requirement for Double Insulation so
an electrical ground connection is not required to meet agency
listings. Actuators shall be UL listed and CSA certified, have
a 5 year warranty, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be as
manufactured by Belimo.
