Overview
SQM45.295A9 is a damper actuator with a nominal output torque of 3 Nm (corresponding to 27 lb-in), a 90° stroke operation time of 10 seconds, and a radial load capacity of up to 190 N. It is suitable for dual 12V AC power supply, which can be powered from the host unit through the bus cable, or can be powered by an independent transformer. Specially adapted to medium and large oil or gas burners, the core is used to control the damper damper of the burner, while achieving precise control of the air and gas ratio. It is a matching component designed for the LMV5 series controller. It can cooperate with the controller to complete the load linkage control of gas flow, oil volume and combustion air volume. It is commonly used in combustion systems of medium and large combustion equipment and thermal processing plants.
FAQ:
1.Is the SQM45.295A9 90° travel time 10 seconds? Are other travel angles optional?
The 90° stroke operation time of the SQM45.295A9 is confirmed to be 10 seconds, and it has no other selectable stroke angle, fixed at 0° – 90°:
- 90° stroke running time: Multiple product parameter information clearly indicates that the running time corresponding to the 90° stroke of this model is 10 seconds, and is paired with a nominal output torque of 3 Nm. This parameter is a key basic parameter for its adaptation to the burner air-fuel ratio control. For example, the product details pages of the Machine Tool Business Network, PLC Hardware and other platforms have clearly disclosed this core parameter.
- Stroke angle optionality: The rotation angle of this model is fixed at 0° – 90°, and there are no other stroke angle specifications available. Its original design is to adapt to the conventional adjustment needs of the damper damper of medium and large burners. This fixed stroke angle can meet the precise control of the air-fuel ratio in this scenario. Although some other models in the SQM series have larger stroke angles such as 160°, this feature does not apply to the SQM45.295A9.
2. What are the differences in core parameters (torque, power supply, protection level) between SQM45.295A9 and the alternative model SQM45.295B9?
| Core parameters | SQM45.295A9 | SQM45.295B9 |
| Nominal output torque | 3 Nm (27 lb-in) | |
| Holding torque | 1.5 Nm | |
| Maximum radial bearing capacity | 190 N | |
| Protection level | IP54 (EN 60529 standard) | |
| Power supply logic | Compatible with LMV5 series controller power supply system | |
| Key extras | No CAN bus communication | Added CAN bus communication (supports intelligent linkage) |
3.What are the applicable scenario limits for SQM45.295A9 radial bearing capacity 190 N?
- It is only suitable for light loads such as medium and large burner dampers and small butterfly valves, and cannot drive heavy/large diameter valves and heavy-duty gear sets;
- Not resistant to high-frequency vibration, combustion pulse impact and axial + radial composite stress;
- It is not possible to retrofit multiple components in series (additional radial load);
- In high dust and high humidity environments, frictional resistance increases, effective bearing capacity decreases, and adjustment hysteresis is prone to occur.
