Braking Devices AC-VersiBrake 25A

Braking Devices AC-VersiBrake 25A

Function:

  • • 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

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

Typical Applications:

  • • sawing machines
  • • centrifuges
