24v 22InLb SR PropActuator| Operation | The TF series actuators provide true spring return operation for reliable fail-safe
application and positive close-off on air tight dampers. The spring return system
provides consistent torque to the damper with, and without, power applied
to the actuator. The TF series provides 95� of rotation and is provided with a
graduated position indicator showing 0 to 95�. The TF uses a brushless DC
motor which is controlled by an Application Specific Integrated Circuit (ASIC)
and a microprocessor. The microprocessor provides the intelligence to the ASIC
to provide a constant rotation rate and to know the actuator?s exact fail-safe
position. The ASIC monitors and controls the brushless DC motor?s rotation and
provides a digital rotation sensing function to prevent damage to the actuator
in a stall condition. The actuator may be stalled anywhere in its normal rotation
without the need of mechanical end switches. Power consumption is reduced in
holding mode |
