Typical Specification
Spring return control damper actuators shall be direct coupled type which require no
crank arm and linkage and be capable of direct mounting to a jackshaft up to a 1.05”
diameter. The actuator must provide proportional damper control in response to a
LonWorks controller. The actuators must be designed so that they may be used for
either clockwise or counterclockwise fail-safe operation. Actuators shall use a
brushless DC motor controlled by a microprocessor and be protected 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 cULus
Approved and have a 5 year warranty, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be as manufactured by Belimo.
