5-steps transformer controller

Application

  • Hand control of the speed of controllable motors

Composition

  • Supply: 230Vac - 50/60 Hz - from 0,8 up to 20 A
  • Enclosure: Plastic / sheet steel, IP54
  • Switch: 5 positions and Off-position
  • Several voltage ranges possible
  • Indicator lamp
  • Current fuse
  • 230 Vac, unregulated output
