Information About SQN90.570A2793
The SQN90.570A2793 is part of the Siemens SQN9 family of burner damper actuators. A synchronous motor drives the output shaft and switching camshaft through a maintenance-free gear train. Adjustable cams establish the operating points of the end and auxiliary switches. The assembly includes position indication and screw terminals within an impact-resistant, heat-resistant plastic housing.
Key Features:
- Burner Damper Positioning: Operates compatible air dampers as part of the burner control arrangement.
- Synchronous Motor: Provides geared rotary movement for the connected damper mechanism.
- Power Consumption: Has a specified apparent power consumption of 8 VA.
- Angular Adjustment: Supports adjustment within a maximum 90° travel range.
- Adjustable Switching Cams: Allows switching points to be set within the working range.
- Position Indication: Provides a visual reference for actuator position during setup.
- Screw-Terminal Wiring: Accepts conductors with cross-sectional areas from 0.5 to 2.5 mm².
- Maintenance-Free Gear Train: Uses a geared transmission that does not require routine lubrication.
The SQN90.570A2793 delivers the reliability and precision required for coordinated combustion-air damper positioning in compatible burner systems.
