AHQX24-MFT-100 Technical Data Sheet
Modulating, Non-Spring Return, Linear, 24 V, Multi-Function Technology®
Linear force min. 44 lbf for control of damper surfaces up to 12 sq.
ft.
Application
For proportional modulation of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The default parameters for 2 to 10 VDC applications of the …MFT actuator are
assigned during manufacturing. If necessary, custom versions of the actuators
can be ordered. The parameters can be changed by two means: pre-set and
custom configurations from Belimo or on-site configurations using the Belimo
PC-Tool software.

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.

Typical Specification
Proportional control damper actuators shall be electronic direct-coupled type,
which require no crank arm and linkage and be capable of direct mounting
to a shaft up to 1.05” diameter. Actuators must provide proportional damper
control in response to a 2 to 10 VDC or, with the addition of a 500 Ω resistor,
a 4 to 20 mA control input from an electronic controller or positioner.
Actuators shall have Brushless DC motor technology and be protected from
overload at all angles of rotation. Actuators shall have reversing switch and
manual override on the cover. Run time shall be constant and independent
of torque. Actuators shall be cULus listed, have a 5-year warranty, and be
manufactured under ISO 9001 International Quality Control Standards.
Actuators shall be as manufactured by Belimo.

A
Provide overload protection and disconnect as required.
Actuators may also be powered by 24 VDC.
Only connect common to negative (-) leg of control circuits.
A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2
to 10 VDC.
Actuators may be connected in parallel if not mechanically linked. Power
consumption and input impedance must be observed.
IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number
40155).
