AHB24-3-200 Belimo Actuator

Application:

For on/off and floating point control of dampers in HVAC systems.
Actuator sizing should be done in accordance with the
damper manufacturers specifications.

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 AHB24…-200 provides 8 in [200 mm] 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 AHB24-3… actuators use a sensorless Brushless DC
motor, which is controlled by an Application Specific
Integrated Circuit (ASIC). The ASIC monitors and controls the
actuators 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.
