Siemens SQN31.401A2760 actuator

Siemens SQN31.401A2760 actuator — basic model for precise control of burner air damper. Siemens SQN31.401A2760 is a compact electromechanical air damper actuator of the SQN31 series, designed for small and medium burners. It provides automatic control of the air-to-fuel ratio, directly affecting combustion efficiency, operating economy, and equipment safety. Application: The actuator is used for automatic regulation of air and fuel damper positions during fuel ignition, burner operation in low and high fire modes, and during combustion chamber purging. The actuator works with Siemens RWF50 controllers and various Siemens LOK16, LGK, LAL, LFL burner controls. It is also compatible with P-PI and PID controllers. Key technical specifications: Power supply: 220 V, 50/60 Hz. Torque: 3 Nm. Power consumption: 6.5 VA. Damper adjustment angle: 0–90°. Opening time to 90°: 30 seconds. Protection class: IP 40. Design and maintenance: The model is basic and comes in a compact housing. Siemens SQN31.401A2760 has a basic design without a potentiometer — if necessary, the device can be upgraded using the additional set AGA32. The steel shaft rotates clockwise, disengages manually from the gear train, re-engagement automatic. Long-life lubrication ensures reliable gear operation without maintenance. The actuator is equipped with easily adjustable switches (end and auxiliary) and position indicators.
