Belimo AFXUP-S N4 Actuator
The Belimo AFXUP-S N4 Actuator is a high-torque, spring return damper actuator engineered for rigorous commercial HVAC and industrial applications. This universal power supply unit operates on a wide voltage range of 24V to 240V AC or 24V to 125V DC, eliminating the need for separate transformers in the field. Built with a robust NEMA 4X (IP66) enclosure, it is specifically designed to handle wash-down environments, high humidity, and outdoor exposure where standard actuators fail. Delivering 180 in-lb of torque, it provides reliable on/off control for large dampers, ensuring a mechanical fail-safe position in less than 20 seconds during power loss. The integrated dual SPDT auxiliary switches allow for precise position proofing, while the manual override simplifies commissioning and emergency manual operation.
Technical Benefits for Contractors
- Universal Voltage Compatibility: The AFXUP-S N4 handles any supply voltage from 24V to 240V, reducing truck stock requirements.
- NEMA 4X Rated Protection: UL Type 4X housing provides superior resistance to corrosion and moisture in mechanical rooms or rooftop units.
- Configurable Fail-Safe: Reliable spring return mechanism ensures dampers close or open as required for smoke and fire safety or freeze protection.
- Dual Auxiliary Switches: Includes two built-in switches (fixed 10° and adjustable 10° to 90°) for auxiliary equipment interlocking.
- High Torque Output: Rated at 180 in-lb (20 Nm) to drive large-area dampers or high-pressure air handling units.
Common Installation Questions
What is the maximum damper size this actuator can handle?
With 180 in-lb of torque, it is generally suitable for dampers up to 45 square feet, though actual sizing depends on damper seal friction and air velocity.
Can the AFXUP-S N4 be used in outdoor cooling tower applications?
Yes, the NEMA 4X / IP66 enclosure is designed for harsh outdoor environments and protection against wind-blown dust and rain.
How do I change the fail-safe direction?
The direction of the spring return fail-safe is determined by the mounting orientation (CW or CCW) on the damper shaft.
