Siemens SQN75424A21
Brief characteristics:	Electrical requirement: 220 V, 50/60 Hz. Torque: 2.5 Nm. Power consumption: 6 VA. Angle adjustment max. 160 °, scale range 0 ... 130 °. Clockwise rotation Duration of opening at 90º: 12 sec. Temperature range: -20 ... + 60 ° С.
DEVICE AND FEATURES	Siemens / Landis servo drives are controlled by burner controls, which are part of the automatic burner devices and allow you to adjust the ratio of gas and air (air and liquid fuel) during the formation of a fuel-air mixture for combustion. The synchronous electric motor is equipped with a blocking protection system. The detachable gear train is automatically reset to its original position. The gear mechanism does not require regular maintenance due to the use of long-life grease. The body is made of heat-resistant, shock-resistant plastic protects working units and electrical elements from external, negative factors. The servo drive is equipped with limit switches, position indication, easy to set up. Possibility of connecting a potentiometer is provided.
