Damper Actuator,180 in-lb,Non-Spring Return,24V,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 AM... 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 AM...24-3? 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.
The AM...24-3-S version is provided with 1 built-in auxiliary switch. This SPDT switch
is provided for safety interfacing or signaling, for example, for fan start-up. The
switching function is adjustable 0 to 95�. The auxiliary switch is double insulated so
an electrical ground connection is not necessary.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto
the actuator body for signaling and switching functions. |

| Typical Specification | Floating point, on/off 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 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, actuators shall be provided with one adjustable SPDT auxiliary switch. Actuators with auxiliary switches must be constructed to meet the requirements for double insulation so an electrical ground is not required to meet agency listings. If required, actuators will be provided with a screw terminal strip for electrical connections (AMX24-3-T). Run time shall be constant and independent of torque. 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. |
