Belimo AMQB24-1 Non-Spring Return Damper Actuator in-lb - 24V 140

The Belimo AMQB24-1 is a non-spring return damper actuator designed for HVAC air control applications. This robust actuator provides reliable modulating control of dampers in commercial heating, ventilation, and air conditioning systems.

Key Specifications:

• 24V AC/DC power supply for flexible installation
• 140 in-lb (16 Nm) torque output for medium to large damper control
• Non-spring return operation maintains damper position on power loss
• Modulating floating control with auxiliary switch output
• 90-degree rotation angle for standard damper applications
• Adjustable auxiliary switch for end position indication or interlocking
• Direct mount design for NEMA dampers
• Durable construction for long-lasting performance

This actuator is ideal for VAV systems, bypass dampers, and mixed air applications where precise airflow control is required. The non-spring return design eliminates the need for battery backup in applications where maintaining damper position during power interruption is acceptable.
