Overview Details for AMB24-3

The Belimo AMB24-3 is a non-spring return damper actuator designed for precise and reliable control of air dampers in HVAC systems. This actuator is suitable for on/off and floating point (modulating) control applications, providing flexibility for various HVAC needs. It operates on 24V AC/DC and delivers 180 in-lb of torque, making it compatible with a range of damper sizes and applications.

The AMB24-3 features direct coupling to damper shafts up to 1.05" in diameter, simplifying installation and eliminating the need for linkages. The non-spring return functionality ensures that the damper holds its last position in case of a power outage, maintaining desired airflow until power is restored. This actuator is equipped with a manual override for convenient damper adjustment during maintenance or emergencies. The AMB24-3 is built with a durable, NEMA 2/IP54 rated enclosure, providing protection against dust and moisture. It's designed for maintenance-free operation and offers a long lifespan, making it a cost-effective solution for reliable damper control.

The AMB24-3 helps optimize energy efficiency and indoor air quality in commercial HVAC systems. The -S version of this actuator (AMB24-3-S) includes an integrated SPDT auxiliary switch for added flexibility in system control and monitoring.

Belimo is amazing

Non-spring return actuator is a situational one, but will do just fine if you know how your system should operate. Great quality product, thanks Belimo
