Belimo AHQ Series Non-Spring Return Damper Actuator

The actuator is not provided with and does not require and limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.

The AHQB(X) series provides 4± [100 mm] of linear stroke. The stroke of the gear rack can be adjusted on both sides in increments of 0.8± [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 AHQB(X)24-MFT-100 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.
