Proportional Amplifier 9-30 V

go to order options

The Proportional Amplifier serves as flow rate regulator for proportional valves. It is used in many hydraulic applications. The microcontrollerbased current regulator provides a constant output current proportional to the set point value 0-10 Volt or 0-20 mA. Fluctuations in supply voltage and temperature are compensated for which ensures constant flow rates. To counteract stiction and hysteresis effects a dither frequency can be added (superimposed small rectangular ripple frequency). Please refer to the section housings and base plates for additional housing options.
