DC converter DC WAVE-R


The DC WAVE -R converters support any industrial application where dc motors are employed. Their compact size and simple construction make the assembling and installation inside the cabinet very easy.

Voltage and frequency

  • All regulators can be supplied with a fixed motor excitation power supply, or, in applications where more accurate regulation of motor excitation current is required, converters may be supplied with variable motor excitation voltage.
  • DC WAVE - R regulators feature a control loop of double speed and current loop type. This type of system guarantees safe operation.
  • Digital inputs and outputs are optically isolated; analogue inputs and outputs are protected with suitable means against a short-circuit to a ground.
  • communication RS485, ProfiBus, CanBus.

Additional module signalling operating conditions

Ensuring full compatibility of the converter DC WAVE-R with Formic -V
  • Use of additional module
  • Signalling zero speed (in duplicate with the converter, but more accurate, adjustable)
  • Signalling incompliance of preset and actual speed (adjustable)
  • Signalization of the preset speed level
  • Signalization of armature current, if exceeding the preset value (adjustable)



Converter excitation

Fixed excitation

In addition to a bridge-type rectifier, the circuit structure includes one current transformer measuring the supplied current.

Variable excitation

Used to regulate motor excitation current. By means of trimmers, the circuit regulates the value of the rated current, minimal current and rated voltage of the armature; analogously to fixed excitation, it is connected to the converter by means of a cable.
