Braking Devices AC-VersiBrake 230/400-6/25/30LT

Function:

  • direct online start via motor contactor
  • overload protection
  • braking current control
  • automatic remanence time optimization
  • braking current infinitely adjustable 10-100%
  • braking interrupt is possible
  • restart 1,2s after braking interrupt
  • braking time adjustable
