| 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 ?? in diameter by means of its universal clamp. 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 AMB24-SR-T N4 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 AMBX24-SR-T N4 actuator uses 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. |

| 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. If required, actuator will be provided with screw terminal strip for electrical connections (AMX24-SR-T and NMX24- SR-T). 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 |
