Belimo SMQ24G-SR – damper actuator

Rotary actuator for positioning dampers in HVAC systems, comparable industrial systems and technical building installations. It is designed for air dampers with an area of up to approx. 3.2 m². The IP66/67 protective enclosure allows outdoor use within the specified ambient temperature range.

Key features and specifications

• Torque: 16 Nm; rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Modulating control: 2...10 V; position feedback signal: 2...10 V.
• Motor running time: 7 s / 90°; rotation angle: max. 95°, with adjustable mechanical stops and a minimum permitted angle of 30°.
• Direction of movement selected by 0/1 switch; mechanical position indicator.
• Manual override by push-button with locking option, beneath the protective enclosure.
• Mechanical connection: universal clamp 12...26.7 mm; electrical connection: 1 m cable, 4x 0.75 mm², FRNC (halogen-free).
• Power consumption during operation: 15 W; at rest: 2 W; power for cable sizing: 26 VA.
• IEC/EN degree of protection: IP66/67; IEC/EN protection class: III, Safety Extra-Low Voltage (SELV).
