DC Brake VersiBrake Series(25A)

Features:
  • DC braking with one-way rectification
  • controlled by microcontroller
  • suitable for all asynchronous motors
  • easy mounting, also for retrofitting into existing plants
  • wear-resistant and maintenance-free
  • special voltages up to 575V (UL: up to 480V) with option �B�
  • for snap-mounting onto 35mm top-hat-rail
  • degree of protection IP 20
Functions:
  • control via motor contactor
  • standstill detection
  • braking current limited to rated device current
  • remanence time optimization
  • braking current infinitely adjustable
  • potential-free output for motor contactor interlocking during braking
  • potential-free output for fault signalling relay

Typical Applications:
sawing machines
centrifuges
wood working machines
textile machines
conveying systems


Accessories:

  • star-delta starting control (D)
