Typical Specification
Spring return control 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 actuator must provide proportional damper control in
response to a 0 to 20 V phasecut control output from an electronic controller or
positioner. The actuators must be designed so that they may be used for either
clockwise or counterclockwise fail-safe operation. Actuators shall have control
direction of rotation switch accessible on its cover. 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 or
master-slave applications. Actuators shall be UL Approved 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.

CAUTION Equipment damage!
Actuators may be connected in parallel.
Power consumption and input impedance must be observed.
3
Actuators may also be powered by 24 VDC.
WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it maybe
necessary to work with live electrical components. Have a qualified licensed electrician
or other individual who has been properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety precautions when exposed to live
electrical components could result in death or serious injury.
