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:

• overvoltage and undervoltage

• overcurrent and pump overload

• lack of water in the well or borehole

Built-in functions allow for tank level monitoring, time delay settings, control of the start interval, and the ability to remotely turn the pump on/off.

Key Features

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

• Maximum current: 30 A

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

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

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

• Operating modes: START / STOP

• Memory of the last device status before shutdown

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

Technical Parameters

• Operating voltage: 150-270 V AC

• Frequency: 50 Hz

• Current range: 1-30 A

• Protection class: IP20

• Operating temperature: -20 °C to +55 °C

• Cable cross-section: Max. 10 mm² (power supply), electrodes up to 2.5 mm²

• Weight: 0.25 kg

• Installation altitude: < 2000 m

Applications

• Protection of submersible pumps against dry running and overload

• Water level control in wells and tanks

• Real-time voltage and current monitoring

• Remote pump activation and deactivation

Important Notes

• Electrodes / water level sensors are not included in the kit - they must be ordered separately

• The controller must be connected according to the manufacturer's diagram

• The liquid must not be flammable or explosive

• Installation temperature must be > 0 °C

• The pump must be grounded

• For the device to function correctly, it is necessary to correctly connect the level relay and remote switch inputs.
