Abstract

Elektronische Dosiervorrichtung mit

  • einer einen elektrischen Antrieb aufweisenden Antriebseinrichtung,
  • mindestens einer von der Antriebseinrichtung antreibbaren Verdrängungseinrichtung zum Pipettieren von Flüssigkeit und
  • einer elektronischen Steuer- und/oder Regeleinrichtung für den Antriebsmotor mit einem Wandler, die eine von einer elektrischen Spannungsquelle gelieferte Speisespannung in eine in der Höhe auf die jeweilige Last der Antriebseinrichtung abgestimmte Versorgungsspannung für den Antriebsmotor umwandelt.
Figure 00000001
Electronic dosing device with
  • a drive device having an electric drive,
  • at least one displacement device which can be driven by the drive device for pipetting liquid and
  • an electronic control and / or regulating device for the drive motor with a converter, which converts a supply voltage supplied by an electrical voltage source into a supply voltage for the drive motor which is matched in height to the respective load of the drive device.
