For continuous delivery

The controller S-KB-4 is recommended for continuous flow control in combination with micro annular gear pump mzr-7241. The 2-Q-DC servo amplifier enables to control the constancy of flow rate via motor speed using the hall sensors of the brushless DC-motor. Speed can be adjusted with an external voltage signal (0 … 10 V).

Advantages

  • Pump controller for continuous delivery
  • Good value 2-Q-DC servo amplifier
  • For brushless DC-motor with digital hall sensors
  • Compact aluminum housing
  • Speed set with external voltage signal or external potentiometer
  • Current delimiter
  • Screw terminal for plug-in of mzr-pump
