short description

Speed controller for recess-mounted installation, maximum loading 1 A

Product description

  • Speed controller for linear control of the fans.
  • Minimum speed adjustable.
  • Function principle: Phase angle control.
  • Recommended distance from radios and televisions: 3 m.
  • Switch on the fans at maximum speed by turning the knob. Turning further reduces the speed.
  • With operating indicator light.
  • VDE-tested.
  • Additional switching contact (230 V) e.g. for controlling a shutter.
  • There can be a physically induced humming noise at lower speeds, through the use of phase angle technology. TRE... 5-step transformers are therefore used for speed control in rooms requiring quiet fan operations.
  • Assembly on walls possible; avoid ceiling installation because of temperature build-up.
