Information About SQN91.570A2793
The SQN91.570A2793 is part of the Siemens SQN9 burner actuator family. Its synchronous motor operates the output shaft and camshaft through a geared transmission. Adjustable switching cams establish the positions required by the connected burner control sequence. Screw terminals and an internal position indicator support wiring and mechanical setup.
Key Features:
- Burner Control Application: Positions compatible dampers used to regulate combustion air or gas flow.
- Clockwise Rotation: Turns clockwise when viewed facing the drive shaft at the specified starting position.
- Defined Output Torque: Provides nominal and starting torque of 2.4 N·m.
- Timed Angular Movement: Completes 90° travel in 24 seconds at 50 Hz.
- AC Supply: Uses the 220–240 VAC supply configuration specified for this model.
- Adjustable Switching Points: Allows cam settings to match the required operating sequence.
- Position Indication: Provides a visual reference for checking actuator position.
- Screw-Terminal Connections: Accommodates conductors from 0.5 to 2.5 mm².
The SQN91.570A2793 delivers the reliability and precision required for coordinated damper movement in compatible burner control systems.
