AMB24-SR | Belimo Modulating Damper Actuator 180 In Lb 24V Non Spring Return

Belimo · Motors & Motion

Description  The Belimo AMB24-SR is a non spring return damper actuator designed to deliver 180 in-lb (20 Nm) of torque for precise modulating airflow control. It operates on AC/DC 24 V power and supports 2–10 V control with position feedback for accurate damper positioning.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category Dampers & Actuators Part Number AMB24-SR Subcategory Damper Actuators Nominal Voltage AC/DC 24 V Nominal Frequency 50/60 Hz Voltage Range AC 19.2…28.8 V / DC 21.6…28.8 V Power Consumption (Operation) 2.5 W Power Consumption (Rest) 0.4 W Transformer Sizing 5 VA Control Signal 2…10 V (4…20 mA with resistor) Input Impedance 100 kΩ (2…10 V), 500 Ω (4…20 mA) Position Feedback 2…10 V Torque Output 180 in-lb (20 Nm) Angle of Rotation Max. 95°, adjustable Running Time (Motor) 95 s / 90° Electrical Connection 18 AWG plenum cable, 1 m, 1/2" NPT Degree of Protection NEMA 2 / IP54 Noise Level 45 dB(A) Weight 2.5 lb (1.1 kg)   Information About AMB24-SR The AMB24-SR is part of Belimo’s AM series of non fail-safe damper actuators developed for reliable modulating control in commercial HVAC systems. It features electronic overload protection across the full 0–95° rotation range to maintain consistent torque and protect internal components from mechanical stress. The actuator supports 2…10 V control and can be configured for 4…20 mA operation using an external resistor, ensuring compatibility with a wide range of building automation systems. A compact housing, selectable motor direction, and manual override push button simplify installation, commissioning, and ongoing service. Key Features Non Spring Return Operation: Provides controlled damper positioning without a fail-safe spring, suitable for applications where power-loss return is not required. High Torque Output: Delivers a constant 180 in-lb (20 Nm) torque to reliably drive medium and large air dampers under varying pressure conditions. Modulating Control Capability: Accepts a 2…10 V control signal with optional 4…20 mA configuration for precise proportional airflow regulation. Electronic Overload Protection: Actively protects the actuator throughout the full rotation range by preventing damage from overload or obstruction. Integrated Position Feedback: Supplies a 2…10 V feedback signal for continuous monitoring and closed-loop control integration. Selectable Direction Of Motion: Motor rotation direction can be set via onboard switch to accommodate different mounting orientations. Manual Override Function: External push button allows manual damper positioning during setup, testing, or maintenance. The AMB24-SR delivers the reliability and precision required for accurate modulating damper control in non fail-safe HVAC applications.
