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 overload of the pump

• Water shortage in the well or borehole

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

Main features

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

• Max. 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, start intervals, number of automatic resets, upper sensor delay)

• Operating modes: START / STOP

• Storage of the last device state before shutdown

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

Technical parameters

• Operating voltage: 150-270 V AC

Application

• Protection of submersible pumps against dry running and overload

• Water level control in wells and tanks

• Real-time monitoring of voltage and current

• Remote on and off control of the pump

Important notes

• Electrodes / water level sensors are not included - 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.

• Pump must be grounded

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