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 protection degree IP55.

Inputs and outputs

  • N. 4-11 (according to the model) inputs for floats or pressure switches;
  • N. 1-8 (according to the model) inputs for motor temperature probes (PTC, N.C.);
  • N. 1-8 (according to the model) probes inputs for the control of water infiltration in the motor oil chamber – NB: it requires interface device module;
