AC 100...240 V mod 20 Nm Runni 0| 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 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 � 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 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-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.

| Typical Specification | Proportional control damper actuators shall be electronic direct-coupled type, which require no crank arm and linkage and be capable of direct mounting to a shaft up to 1.05? diameter. Actuators must provide proportional damper control in response to a 2 to 10 VDC or, with the addition of a 500 � resistor, a 4 to 20 mA control input from an electronic controller or positioner. Actuators shall have brushless DC motor technology and be protected from overload at all angles of rotation. Actuators shall have reversing switch and manual override on the cover. Run time shall be constant and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position indication. Actuators shall be cULus listed, have a 5-year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo. |
