Description
SAUTER AVM234SF132
Technical Specifications 24V AC/DC power supply; accepts 0-10V analog control signal; proportional continuous modulation output; rated torque matched with medium-size air dampers; built-in auxiliary feedback potentiometer for position signal output; operating temperature -20°C to +50°C; IP54 protection rating; adjustable rotation angle limit.
Functional Features Receive 0-10V analog control setpoint signals from building automation controllers. Convert control signals into rotary mechanical movement to adjust damper opening angle. Output analog position feedback signal reflecting actual damper opening to the controller. Provide adjustable mechanical limit to restrict maximum and minimum rotation angle. Maintain damper position stably when control signal remains unchanged. Support manual override function for on-site debugging and maintenance.
Application Scenarios Commercial building air conditioning duct dampers, ventilation system air volume adjustment, fresh air unit damper control, smoke ventilation system auxiliary air dampers, clean room HVAC air flow regulation.
Performance Parameters Smooth proportional rotation without obvious jitter; high positioning repeatability of damper angle; stable holding torque under air duct wind pressure; consistent position feedback linearity.
Material Composition Internal reduction gear set adopts high-strength engineering plastic; drive motor is low-noise permanent magnet DC motor; housing is die-cast aluminum alloy with powder coating; output shaft uses stainless steel; internal position feedback component is precision conductive plastic potentiometer.
Structural Characteristics Compact rectangular housing structure with side output drive shaft. Mounting bracket matches standard air damper shaft connection dimensions. Front panel has manual override knob and rotation angle limit adjustment screws. Internal layout integrates drive motor, reduction gearbox and position feedback assembly.
Working Principle The actuator compares the received 0-10V control signal with the actual damper position feedback signal. The internal controller drives the motor and reduction gear set to rotate the output shaft until actual position matches the control setpoint. The feedback potentiometer outputs real-time position voltage signal to the building controller to form closed-loop angle control.
Installation Requirements Fix the actuator mounting bracket on the air damper shaft end and fasten fixing screws. Connect 24V AC/DC power supply, control signal cable and feedback signal cable to terminal blocks. Adjust mechanical rotation limit screws to set maximum and minimum damper opening. Calibrate position feedback range after installation and conduct full stroke test.
Precautions for Use Do not select this actuator for dampers requiring torque higher than rated value. Protect the housing from continuous water splash and corrosive gas. Avoid frequent full-stroke cycling beyond design service cycle. Disconnect power supply before manual adjustment and wiring modification.
