Lin Act 34lbf 4in 2-10V| Application | For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer?s specifications. 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 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 LHB(X)24-SR... series provides 4 or 8 in of linear stroke. The stroke of the gear rack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of the mechanical end stops. 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 LHB(X)24-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. |
