Belimo Damper Actuator, Non-Spring Return, 3 Position, 24V

Belimo Damper Actuator Non Spring Return 3 Position 24v Damp.Rotary, 360in-lb, On/Off/Float, 24V

Torque min. 360 in-lb for control of damper surfaces up to 90 sq ft.
Application
For on/off and floating point control of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft.
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 GMB(X) series provides 95° of rotation and a visual indicator indicates position of
the actuator. 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 GMB(X)24-3… actuators use a 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
