BELIMO Damper Actuator: Dampers, On/Off, Spring Return, 90 in-lb

The BELIMO NFBUP-S is a fail-safe damper actuator with spring return, used for on/off control of HVAC dampers in commercial buildings. Its 90 in-lb torque and plenum rating make it suitable for air-handling units and zone control where spring-return failsafe operation is required.

The BELIMO NFBUP-S operates on 24 to 240V AC/24 to 125V DC with a 9.5VA power rating. It provides 90 in-lb torque, 0 to 95° stroke with CW/CCW rotation, and includes two auxiliary switches. It is plenum rated, hardwired, and not compatible with building automation systems.
