1.230,00 1.000,00 excl. tax

BD1 interface is an essential device used to power eddy current dyno brake. It carries out the following tasks:

  • Mains AC to DC conversion to power the brake winding.
  • Brake power regulation according to received logic-level PWM signal.
  • Load cell signal amplification to 0-5V level.


  • Supply: 85-305VAC, 50-60Hz, 1-3 phase
  • Brake peak current 32A
  • Thermal protection
  • Maximum PWM signal frequency: 2500Hz
