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

Product description

The TENSE MDK-03 control unit is designed for the protection and control of single-phase submersible pumps up to 4 kW.
It provides protection against:

• overvoltage and undervoltage

• overcurrent and pump overload

• lack of water in a well or bore

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

Main functions

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

• Maximum current: 30 A

• Microprocessor control with LED display of 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, start intervals, number of auto-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

• Power consumption: < 6 W

• Fluid sensitivity: < 50 kΩ

• 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 height: < 2000 m

Application:

• Protection of submersible pumps against dry running and overload

• Water level control in wells and tanks

• Real-time voltage and current monitoring

• Remote pump on/off

Important notes

• Electrodes/water level sensors are not included - they must be ordered separately.

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

• The fluid 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 properly connect the inputs of the level relay and the remote switch.
