Siemens Combustion SQM50.480A1Z3 Actuator
The Siemens SQM50.480A1Z3 is a high-torque industrial combustion actuator engineered for precise damper positioning and fuel-air ratio control. Operating on 120V AC, this reversible electromotoric actuator delivers a rated torque of 15 Nm, making it a standard choice for modulating burner control on large-scale commercial and industrial systems. With a running time of 30 seconds for 90 degrees, it provides the steady, repeatable motion required for stable combustion. This specific unit features 8 auxiliary switches for advanced sequencing, interlocking, and status feedback to the Burner Management System (BMS). Designed for versatility, the SQM50 series allows for easy integration into existing linkageless or mechanical linkage setups. Note that this model is supplied without a drive shaft, allowing technicians to select the specific shaft required for their application. The rugged housing and high-grade geartrain ensure reliable performance in high-heat environments typically found in boiler rooms and process heating facilities.
Key Benefits for Contractors
- Precise Control: Maintains exact combustion air damper and valve positioning for maximum fuel efficiency.
- High Integration: Equipped with 8 internal auxiliary switches for complex control logic and signaling.
- Electronic Positioning: Optimized for modulating duty, reducing hysteresis compared to older mechanical units.
- Universal Compatibility: Works seamlessly with Siemens LMV5 and other high-end combustion controllers.
- Industrial Durability: Die-cast aluminum housing and IP54 protection rating for demanding mechanical rooms.
Common Questions
Does the SQM50.480A1Z3 include the shaft?
No, this actuator is supplied without a shaft. You must order the appropriate drive shaft separately based on your specific valve or damper linkage requirements.
Can this actuator be used with a 24V control signal?
The SQM50.480A1Z3 is a 120V AC unit. Ensure your control circuit and power supply match these specifications before installation.
Are the auxiliary switches adjustable?
Yes, the 8 built-in switches are fully adjustable, allowing for precise setting of switching points throughout the 0 to 130-degree rotation range.
