The Belimo NMB24-SR is a 24V non-spring return, modulating damper actuator delivering 90 in-lb of torque. Proportional modulation of HVAC air dampers up to roughly 22 square feet. Non-spring return (maintains last position upon power loss). Sensorless brushless DC motor controlled by an Application Specific Integrated Circuit (ASIC) with Digital Rotation Sensing (DRS) to protect against stalls.
Specifications
Torque: 90 in-lb [10 Nm]
Power Supply: 24 VAC (±20%, 50/60 Hz) or 24 VDC (±10%)
Power Consumption: 2.5 W running / 0.4 W holding
Control Signal: 2 to 10 VDC (4 to 20 mA with a 500Ω resistor)
Feedback Signal: 2 to 10 VDC for position indication
Angle of Rotation: Maximum 95°, adjustable with mechanical stop
Runtime: Constant 95 seconds independent of load
Enclosure Rating: IP54, NEMA 2, UL Enclosure Type 2
Ambient Temperature Range: -22°F to 122°F (-30°C to 50°C)
