Single-phase submersible pump controller for boreholes TENSE MDK-02, 140–280 V AC, 60 A

Product description

The TENSE MDK-02 controller is designed for protection and control of submersible pumps for boreholes and wells.
Provides protection against voltage and current surges, water shortage, and pump overload.
Built-in functions also allow tank level monitoring, adjustment of time delays, and surge current regulation.

Important warning

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

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

• The liquid must not be flammable or explosive

• Installation temperature must be > 0 °C

• The pump must be grounded

• Using two level sensors requires proper connection of the upper and middle sensors
