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.
It provides protection against:

• over- and undervoltage

• overcurrent and pump overload

• lack of water in the well or borehole

Built-in functions provide tank level monitoring, timing adjustments, start interval control, and remote pump ON/OFF capability.

Key Features

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

• Maximum current: 30 A

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

• Protection functions: overvoltage, undervoltage, overcurrent, undercurrent, water level control

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

• Operating modes: START / STOP

• Memory of the last device state before disconnection

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