DC Brake VersiBrake L (LP) 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
  • printed circuit-board version with fault signalling contact
  • for snap-on mounting onto 35mm DIN rail
  • degree of protection: case version IP 20, printed circuit-board version (LP) IP 00
  • meets trade assoc. requirements for category 2 acc. to EN 954-1 acc. to the test principles of woodworking machines GS-HO-01
Functions:
  • start braking via detection of motor voltage and via motor contactor (double safety)
  • overload protection
  • braking current cutoff after motor standstill
  • braking current control
  • automatic remanence time optimization
  • braking current infinitely adjustable 10-100%
  • potential-free output for motor contactor interlocking during braking; also usable to energize the star contactor during braking
  • standstill threshold adjustable; individual adaptable to different motor types

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