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 offers protection against:

• Overvoltage and undervoltage

• Pump overcurrent and overload

• Water shortage in the well or borehole

Built-in functions allow monitoring of the tank level, setting of time delays , control of the start interval and the ability to switch the pump on and off remotely .

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

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

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

• Operating modes: START / STOP

• Saving the last device state before shutdown

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

Technical parameters

Important instructions

• Electrodes/water level sensors are not included in the scope of delivery - they must be ordered separately.

• The control unit must be connected according to the manufacturer's wiring diagram.

• The liquid must not be flammable or explosive.

• The installation temperature must be > 0 °C.

• The pump must be grounded.

• Correct wiring of the inputs for the level relay and the remote switch is necessary for the correct operation of the device.
