  • Power Consumption for Wire Sizing: 4 VA
  • Connection Supply / Control: Cable 1 m, 4x 0.75 mm²
  • Parallel Operation: Yes (note the performance data)

 

Functional Data:

  • Torque Motor: 20 Nm
  • Operating Range Y: 2...10 V
  • Input Impedance: 100 kΩ
  • Position Feedback U: 2...10 V
  • Position Feedback U Note: Max. 1 mA
  • Position Accuracy: ±5%
  • Direction of Motion Motor: Selectable with switch 0/1

Safety Data:

Protection Class IEC/EN: III, Safety Extra-Low Voltage (SELV)

Power Source UL: Class 2 Supply

Degree of Protection IEC/EN: IP54

Degree of Protection NEMA/UL: NEMA 2

Enclosure UL: Enclosure Type 2

EMC: CE according to 2014/30/EU

Low Voltage Directive: CE according to 2006/95/EC

Certification IEC/EN: IEC/EN 60730-1 and IEC/EN 60730-2-14

UL Approval: cULus according to UL60730-1A, UL60730-2-14 and CAN/CSA E60730-1

 

Environmental Data:

  • Hygiene Test: According to VDI 6022 Part 1 / SWKI VA 104-01, cleanable and disinfectable, low-emission
  • Type of Action: Type 1
  • Rated Impulse Voltage Supply / Control: 0.8 kV
  • Pollution Degree: 3
  • Ambient Humidity Max.: 95% RH, non-condensing
  • Ambient Temperature: -30...50°C [-22...122°F]
  • Storage Temperature: -40...80°C [-40...176°F]
  • Servicing: Maintenance-free
  • Weight: 0.95 kg

 

Operating Mode: The actuator connects with a standard control signal of 0...10 V, driving to the position defined by the control signal. The measuring voltage U serves for the electrical display of the damper position 0...100% and as a control signal for other actuators.

Simple Direct Mounting: Easy mounting on the damper shaft with a universal shaft clamp supplied with an anti-rotation device.

Manual Override: Manual override with push-button is possible, disengaging the gear train as long as the button is pressed or remains locked.

Adjustable Angle of Rotation: Adjustable angle of rotation with mechanical end stops.

High Functional Reliability: Overload protection ensures the actuator stops automatically when the end stop is reached.

 

Electrical Accessories: Auxiliary switches, feedback potentiometers, signal converters, and positioners for various mounting options.

 

Mechanical Accessories: Actuator arms, shaft extensions, ball joints, damper crank arms, shaft clamps, anti-rotation mechanisms, form fit inserts, mounting kits, and position indicators.
