101 lbf [450 N force]
For proportional modulation of dampers in HVAC systems. The AHKX24- MFT-100 provides electrical power off operation for reliable fail-safe application.
The default parameters for 2 to 10 VDC applications of the AHKX24-MFT-100 actuator are assigned during manufacturing. If necessary, custom versions of the actuators can be ordered. The parameters can be changed by: pre set or custom confi gurations provided by Belimo or on-site using the PC-Tool software.
The actuator is electronically protected against overload.
The AHKX24-MFT-100 provides a 4 inch linear stroke. The stroke of the gear rack can be adjusted on both sides in increments of 0.8 in [20mm] with the mechanical end stops.
When reaching the damper or actuator end position the actuator automatically stops. The gear can be manually disengaged by pressing the button located on the actuator cover.
The AHKX24-MFT-100 actuator uses a brushless DC motor controlled by an Application Specifi c Integrated Circuit (ASIC). The ASIC monitors and controls the actuator rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in a holding mode.
The status LED on the actuator will turn solid yellow. On MFT versions, there is a repeating high-low-high signal on the feedback line. The high-low-high signal will display for 3 seconds and repeats every 30 seconds.
