Attuatore Siemens SQN72.2A4B20

Compact servo drive Siemens SQN72.2A4B20 for small power burners Fast and precise air damper control in 4 seconds Siemens SQN72.2A4B20 is a reliable electromechanical actuator (servomotor) for precise control of the air damper in gas burners of small and medium power. The model is specially designed for burner automation systems and is ideally compatible with Baltur burners (specification "BT" in the designation). If you need a compact, fast and energy-efficient device for your boiler room, SQN72.2A4B20 is the optimal choice. Key advantages Record speed - 90° rotation time is only 4 seconds. This ensures lightning-fast burner start-up and precise response to load changes. Energy efficiency - power consumption is only 6 VA. Minimal power consumption reduces operating costs and allows the actuator to be used in systems with limited energy resources. Wide adjustment range - the damper can open at angles from 0° to 160°, providing flexibility for different burner operating modes. Reliable protection against external influences - protection class IP54 guarantees actuator operability in dusty and humid boiler rooms. Ease of adjustment and maintenance - the gear transmission requires no maintenance or lubrication throughout its entire service life. If necessary, the shaft can be easily disconnected from the gearbox manually. Convenient mounting - the housing has technological holes for fixing and connection, a plug-in connection for electrical contacts is provided.
