● The actuators are used primarily for the load-dependent control of the
gas flow, oil volume and combustion air volume in connection with the
electronic ratio control LMV5.
● Areas of application are oil and gas burners of medium to larger capacity,
as well as thermal process plants.
● The actuators SQM9 are suited for driving oil pressure controllers,
butterfly valves, dampers or for use on other applications that
require rotary motion.
●Standards & Certifications:
● The actuators are of rugged design and have a gear train with only little backlash.
● Control and position feedback take place via a bus system (CAN). The bus cable is also used for powering the actuators.
● The actuators are driven by stepper motors and can be positioned with a resolution of 0.1°.
● Operating voltage AC 2 x 12 V
● Power consumption Approx. 40 VA at rated mains voltage
● Angular adjustment Max. 0...90°
● Reproducibility of actuator positions across the usable angular range of 0...90° ±0.8°
● Safety class III (as per DIN EN 60730-1)
● Degree of protection IP66 as per EN 60529, provided adequate cable entries are used
● Environmental conditions Operation IEC 60721-3-3
Climatic conditions Class 3K3
Mechanical conditions Class 3M3
Temperature range -20...+60 °C
