Electronic control panel with microprocessor available in single or three phase version, equipped with electronic protection against dry running and integrated pump exchanger.

It is easy to install and start thanks to motor current and cosφ self-calibration.

It is suitable for surface pumps, submerged pumps and motors in general, with power range between 0,09 kW and 18,5 kW (please download the data sheet to learn more about all the available sizes and features). It can be used for emptying, filling and pressurization.

Electronic control panel with thermoplastic case and IP55 protection degree.

Inputs and outputs

  • N. 4-7 (according to the model) inputs for floats or pressure switches;
