Damper Actuator | 45 in-lb | Non-Spg Rtn | 24V | Modulating
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 from 1/4” up to 5/8” in diameter by means of its universal clamp. Shafts up to 3/4” diameter can be accommodated by an accessory 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.
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 LMB 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 LMB24-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.
Ive started purchasing a few of these LMB24-SR-T Damper Actuator since I began renovating our beloved home. You know what, its very good what it does. Its power tolerance for AC and DC are wide enough, but it consumes less anyway. Because this device is properly and electronically insulated, this valve actuator can be safely interacted within the maximum rotation of 90 degrees. It also contains a smart heater and thermostat so the device doesnt get condensed. It is smart, right? Thats because I can remotely access it using my phone. Great.
