Submersible pump control relay, well tank level indicator

Three-phase submersible pump control and protection, maximum current 60 A, 260 V-470 V AC, Voltage.

Electrodes (liquid level sensors) are not included.

Monitoring of maximum and minimum current and voltage, monitoring of water presence, star/delta start, inrush current factor, start time setting, on/off delay timers, return to work timer, inputs for three level sensors and float switch, asymmetry and phase sequence monitoring, 4 x 20 character LCD display, dry-run protection and automatic cyclic function.

This controller is designed for the automation of protection and control of submersible boreholes and other water pumps. The main features of this controller are:

- Large, easy-to-read display for information and setting operating parameters.

- Intuitive interface

- Buttons for manual pump control

- Monitoring of maximum and minimum voltage between phases (with adjustable time and nominal values).

- Monitoring of maximum and minimum current (with adjustable time and nominal values)

- Setting of time interval and overload factor for current switching

- No need to connect a neutral wire

- Monitoring of phase sequence and phase asymmetry (with adjustable time and nominal values)

- Built-in star-delta start relay for reducing inrush currents

- Adjustable power factor values for dry-run protection even if water level sensors are not used

- Adjustable sensor sensitivity depending on water parameters

- Adjustable response time for level sensors

- Pulse power supply for level sensors - significantly extends sensor life

- Regulation of pump activation frequency and operating time saving even during power outages

- Saving of error log in non-volatile memory
