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 up to 1.05”
in diameter by means of its universal clamp, 1/2” self-centered
default. A crankarm 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 actuator is not provided with and does not require any
limit switches, but is electronically protected against overload.
The anti-rotation strap supplied with the actuator will prevent
lateral movement.
The TAMB series provides 95° of rotation and a visual indicator
indicates position of the actuator. When reaching the damper or
actuator end position, the actuator automatically stops. The gears
can be manually disengaged with a button on the actuator cover.
The TAMB24-SR… actuators use a sensorless brushless DC
motor, which is controlled by an Application Specific
Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing
(DRS) function to prevent damage to the actuator in a stall
condition. Power consumption is reduced in holding mode.
Add on auxiliary switches or feedback potentiometers are
easily fastened directly onto the actuator body for signaling
and switching functions
