Control and protection of three-phase submersible pump, maximum current 60 A, 260 V-470 V AC, Tense.

Electrodes (liquid level sensors) not included.

Maximum and minimum current and voltage monitoring, water presence monitoring, star/triangle starting, inrush current factor, start-up time setting, on/off delay timers, return to service timer, inputs for three level sensors and float switch, asymmetry and phase sequence monitoring, 4x20 character LCD display, dry run protection and automatic cycling.

This controller is designed to automate the protection and control of submersible drilling and other water pumps. The main features of this controller are:

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

• Intuitive interface

• Buttons for manual pump control

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

• Maximum and minimum current monitoring (with adjustable time and nominal values)

• Setting of time interval and overload factor for switching current

• No need to connect neutral wire

• Phase sequence and phase asymmetry monitoring (with adjustable time and nominal values)

• Built-in star-delta start relay to reduce inrush currents

• Adjustable power factor values for dry-running protection even when water level sensors are not used

• Adjustable sensor sensitivity based on water parameters

• Adjustable response time for level sensors

• Pulse power supply for level sensors - significantly extends sensor lifetime

• Adjust pump activation frequency and save run time even during power failure

• Error log storage in non-volatile memory
