● The SQN1 actuators are used to drive and position air / gas dampers or
other ancillary equipment. When used in connection with burner controls
or electronic fuel / air ratio control, the controlling elements are operated
depending on the current burner output.
● Standards & Certifications:
● The SQN1 actuators features an integrated reset spring with backlash-free gear train.
● The same cable serves for control and position feedback.
● The actuators are driven by a stepper motor and can be positioned with a resolution of 0.1°.
● The running times of the controlling elements are varied by the basic unit depending on the burner's control phase
