Damper Actuator,180 in-lb,Non-Spring Return,100 to 240V,On/Off/Floating Point| Application | For on/off and floating point control 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, self-centered default. A crank arm and several mounting
brackets are available for applications where the actuator cannot be direct coupled to
the damper shaft. |

| 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 AMX 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 AMX120-3 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. |
