Alphafluid Hydrauliksysteme Müller GmbH

- Logic Amplifier Serves


The AlphaFluid logic amplifier serves to select proportional solenoids; in particular, to position and/or control the AlphAktor (AlphActuator) and other AphaFluid products as well as proportional hydraulic systems in general. The amplifier is based on microcontroller technology and can be universally used due to a wide variety of parametrization possibilities. A power amplifier serves for selection of the proportional solenoid and supplies the adjusted current. The pulse width-modulated selection ensures the necessary oscillation/resonance of the control spool within the proportional valve. The desired current is controlled at the PWM frequency and the change in resistance is compensated by the temperature change at the proportional solenoid. The logic amplifier is suitable for operating voltages of 12V and 24V.

  • Power amplifier for proportional solenoid (e.g. AlphAktor)
  • Suitable for 12 V and 24 V
  • Easy parameterization
  • Housing for 35 mm standard top-hat rail mounting
  • Internal digital processing
  • Reference voltage selectable 5 V and 10 V
  • Input 'setpoint' signals: 0..5 V, 0..10 V and 0..20 mA
  • Input 'Pos1' / 'Pos2' for saving current values/position value (non-volatile)
  • Input 'approval' for activation of the amplifier stage
  • Output 'system' indicates function standby
  • Output 'state' indicates the setpoint = actual value (+/- 0.5%)
  • 8 different speeds selectable
  • Retraction and extension speed separately selectable
  • Current limits adjustable via multiple speed potentiometer (Imin/Imax)
  • 8 PWM frequencies adjustable
  • Actuator limitation: allows reducing of speeds and linear movements
