I20683 - Subject to change.
Torque min. 35 in-lb, for control of air dampers
Application
For proportional modulation of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper
manufacturer’s specifications.
The actuator is mounted directly to a damper shaft from 3/8”
up to 1/2” in diameter by means of its universal clamp, 1/2”
shaft centered at delivery. For shafts up to 3/4” use K6-1
accessory. A crank arm and several mounting brackets are
available for applications where the actuator cannot be direct
coupled to the damper shaft.
The actuator operates in response to a 2 to 10 VDC, or with the
addition of a 500
Ω
resistor, a 4 to 20 mA control input from an
electronic controller or positioner. A 2 to 10 VDC feedback signal
is provided for position indication or master-slave applications.
Operation
The TLF 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 TLF series provides 95° of rotation and is provided with a
graduated position indicator showing 0° to 95°.
The TLF24-SR 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 actu-
ator 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.
For all accessories, see pages 110 and 132.
