Siemens SQN71.244B20 actuator

Siemens SQN71.244B20 actuator — speed and precision for Lamborghini burners. The Siemens SQN71.244B20 actuator is a specialized actuating device for automatic control of the air damper in Lamborghini burner systems. It opens and closes the damper during fuel ignition, regulates air supply during fuel-air mixture preparation, and participates in combustion chamber purging — all automatically, on command from the burner controller. The SQN71.244B20 model is the current replacement for the previous generation SQN71.244A20 and is fully compatible with it in terms of mounting and electrical parameters. Where it is used: The actuator is specially designed for small and medium power Lamborghini burners operating on gas or liquid fuel. Belonging to the SQN71 series guarantees perfect structural compatibility with this manufacturer's equipment without any modifications during installation. Technical specifications: Power supply: 220–240 V, 50/60 Hz. Torque: 1.5 Nm. Power consumption: 6 VA. Adjustment range: 0–130°. Maximum rotation angle: 160°. Opening time to 90°: 4 seconds. Operating temperature range: –20 to +60°C. Protection class: IP40. Dimensions: 11.7×6.6×9 cm. Weight: 0.5 kg. Design advantages: Reversible synchronous motor provides rotation in both directions. The design includes end and auxiliary switches with easy manual adjustment. Built-in position indication simplifies operation and monitoring. Heat-resistant impact-resistant polymer housing and shaft made of wear-resistant steel ensure reliable operation under high temperature and vibration loads. Why choose this model: The main difference of SQN71.244B20 from other models in the series is the record short time
