DC Brake VersiBrake LT Series(6-30A)

Features:
  • DC braking with one-way rectification
  • suitable for all asynchronous motors and for mono phase motors
  • controlled by microcontroller
  • easy mounting, also for retrofitting into existing plants
  • wear-resistant and maintenance-free
  • integrated braking contactor
  • for snap-on mounting onto 35mm DIN rail
  • degree of protection IP 20
  • successor for braking devices type BR and BR-L
Functions:
  • 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
  • potential-free output for motor contactor; interlocking during braking; also usable to energize the star contactor during braking
