Description
The Siemens SQM50.380A1 is an electromechanical actuator that drives air and gas dampers in oil- and gas-fired burners of medium to large capacity. It regulates gas flow, oil volume, and combustion air volume in response to load demand. The actuator operates with 3-position or modulating controllers and can be driven directly by burner controls.
It produces 15 Nm of torque and travels up to 130°, reaching 90° in 15 seconds and 130° in 22 seconds at 50 Hz. Eight auxiliary switches signal position. The unit indicates position both internally and externally, and the drive shaft and camshaft disengage separately for setup.
