Belimo NKQB24-1 Actuator
The Belimo NKQB24-1 Actuator is a high-speed, electronic fail-safe damper actuator designed for reliable on/off control in mission-critical HVAC installations. Operating on 24VAC/DC, this unit delivers 54 in-lb of torque and features a rapid 4-second running time, making it ideal for applications requiring immediate response. Unlike traditional spring-return models, the NKQB24-1 utilizes integrated capacitors to drive the damper to its programmed safety position during a power loss, ensuring consistent emergency shutdown performance. The brushless DC motor is controlled via a custom ASIC to provide overload protection and maintain constant torque throughout the 95-degree rotation range. Designed for direct mounting on damper shafts up to 1.05 inches, this high-torque HVAC actuator simplifies field installation with its universal clamp and manual override button. Its rugged NEMA 2 construction and terminal strip connections ensure long-term stability in commercial air handling units and zone control systems.
Key Benefits
- Electronic Fail-Safe System: Utilizes maintenance-free capacitors instead of mechanical springs for reliable fail-safe actuator positioning.
- High-Speed Operation: A 4-second drive time enables rapid adjustments for fast-acting damper control and pressure stabilization.
- Universal Compatibility: Operates on both 24V Class 2 circuits and DC power supplies for versatile field integration.
- Low Power Consumption: Efficient brushless DC motor technology reduces transformer sizing and operational costs.
- Simplified Commissioning: Standardized terminal strip and direct-coupled mounting reduce labor time on the job site.
Common Questions
How do I change the fail-safe direction on the NKQB24-1?
The fail-safe direction (normally open or normally closed) is typically adjusted via a physical switch located under the actuator cover, allowing you to select the return position upon power loss.
Can this actuator be used in smoke or fire safety applications?
No, the Belimo NKQB24-1 is intended for general HVAC automation. Specialized UL-555S rated actuators must be used for dedicated fire and smoke dampers.
Is a separate linkage kit required for installation?
This is a direct-coupled actuator designed to slide directly onto a standard damper shaft. A linkage kit is generally only required for crank-arm or retrofit applications.
