Siemens SQN71.424B20 actuator

Siemens SQN71.424B20 actuator — specialized solution for Lamborghini burners. The Siemens SQN71.424B20 actuator is an actuating device created specifically for controlling the air damper in Lamborghini burners. It regulates the air supply when preparing the fuel-air mixture before entering the burner, opens and closes the damper during ignition, and ensures high-quality purging of the combustion chamber. Model SQN71.424B20 is the current replacement for the previous generation SQN71.424A20 and is fully compatible in mounting and electrical parameters. Where it is used: The actuator is specially designed for Lamborghini burner devices of small and medium power operating on gas or liquid fuel. Belonging to the SQN71 series means the device is optimized for a specific structural group of burners, ensuring perfect compatibility without any adaptations. Technical specifications: Power supply: 220–240 V, 50/60 Hz. Torque: 2.5 Nm. Power consumption: 6 VA. Adjustment range: 0–90°. Maximum rotation angle: 160°. Opening time for 90°: 12 seconds. Operating temperature range: –20 to +60°C. Protection class: IP40. Dimensions: 11.7×6.6×9 cm. Weight: 0.5 kg. Design advantages: The reversing synchronous motor provides rotation in both directions. The design is equipped with limit and auxiliary switches with convenient manual adjustment. Built-in position indication simplifies control and maintenance. The housing made of impact-resistant heat-resistant plastic and the drive shaft made of wear-resistant steel guarantee durability even under high temperatures and intensive use. Why choose this model: The SQN71 series are specialized Siemens actuators created
