Damper Actuators

Comprehensive torque offering (18 in-lbs to 360 in-lbs), with direct coupled, linear or rotary actuators that can handle many applications. All non-spring return actuators use brushless DC motor technology, which is controlled by an Application Specific Integrated Circuit (ASIC). Minimum torque guaranteed over entire specified operating range; no loss in performance due to temperature, supply voltage or speed. Electronically protected against overload. Low power consumption provides higher efficiency and smaller transformer sizing.

Comprehensive torque offering (22 in-lbs to 270 in-lbs) over a vast selection of actuators for a wide range of applications. True mechanical spring return, providing reliable fail-safe. Manual override crank eases installation (all EF, AF and NF series only). Low power consumption provides higher efficiency and smaller transformer sizing. Minimum torque guaranteed over entire specified operating range, no loss in performance due to temperature or supply voltage. MFT is available in all spring return actuators, giving the user the flexibility to customize and adapt a single actuator to various controllers and 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 AHB(X)... series provides 4, 8, or 12 inches 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 AHB(X)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
