TENSE MDK-03 single-phase submersible pump controller, 150-270 V AC, 30 A

Product description

The TENSE MDK-03 control unit is designed to protect and control single-phase submersible pumps up to 4 kW.
Provides protection against:

• overvoltage and undervoltage

• overcurrent and pump overload

• water shortage in the well or borehole

Built-in functions provide tank level monitoring, time delay settings, start interval control, and the option for remote pump on/off control.

Key features

• Single-phase power supply: 150-270 VAC, 50 Hz

• Maximum current: 30 A

• Microprocessor control with LED display for voltage, current, and electrode status

• Protective functions: overvoltage, undervoltage, overcurrent, low current, water level control

• Adjustable operating parameters: P1-P12 (e.g., voltage, current, response delay, start intervals, number of automatic resets, upper sensor delay)

• Operating modes: START / STOP

• Memory of the device's last state before shutdown

• Indication of electrode immersion in water (upper - red indicator, lower - yellow indicator)
