Technical data

  • Power consumption:
  1. In operation: 6,5 W @ nominal torque SFA-(S2)
  2. At rest: 3.5 W SFA-(S2)
  3. For wire sizing: 18 VA SFA-(S2)
  • Direction of rotation: reversible by mounting
  • Angle of rotation: max. 95° , limited on both sides by means of adjustable, mechanical end stops. The actuator is overload proof; requires no limit switches and automatically stops when the end stop is reached
  • Running time motor: <75 s
  • Running time spring return: <60 s
  • Sound power level: max. 62 dB (A)
  • Degree of protection: IP54 in any mounting position
