OPDC converter is the solution offered by BDF Digital for the direct current control.
The new OPDC belongs to OPDE family and inherits all its features, it is an unidirectional and bidirectional full digital converter for two/four quadrants drives that can control currents up to 600A


  • High performance motor control:
    – 32 bit floating-point mlcroprocessor
    – Current sampllng time: 10 μs
    – Speed and Posltlon controller update every 40µs
  • Easy to use Autotune features for armature, field current loop
  • Two different armature current controls available:
    – Model Predictive Control (MPC)
    – Proportional lntegrator Control
  • Internal fleld controller with intelligent field weakening and external power box up to 25A for single phase supply voltage
  • Galvanlc lsolatlon between power and control protects the control circuits and other equipment connected to the drive from the high voltages on the power circuit
  • Three optional slots for I/0 Expanslon, Fleldbus communlcatlons and for the management of feedback sensors:
    – Dinamo tachimetrica
    – Encoder incrementali
    – SinCos, Hiperface e Endat
