Simple and Compact DIN rail Mount Controller for Submersible single phase Pump, for deep well and tank water levels, MDK-03

The Tense MDK-03 is a digital, monophase submersible pump control relay manufactured by Tense Electronics. It is specifically engineered to manage and protect single-phase electric motors and submersible pumps used in water well-pump-tank combination and similar environments.

The device actively monitors electrical parameters to safeguard your pump from costly damage by offering:

• Dry-Running Protection: Monitors liquid levels via electrode connection to prevent waterless operation.
• Voltage Protection: Safeguards against both under-voltage and over-voltage conditions (Operating range: 150V–270V).
• Current Protection: Protects against over-current (overload) and under-current issues using its internal current transformers.
• Built-in Contactor: Includes an internal contactor capable of handling direct operations from 1A up to 30A.
• Start/Stop Memory: Features a continuation function that allows the pump to resume from its last working position after a power or system interruption. 

Technical Specifications Overview

Adjustable Parameters

• Error Waiting Time: The period the system waits before logging an official fault.
• Auto Reset Time & Count: Settings for how many times and how frequently the device attempts a self-reset after a fault clears.
• Demurrage Multiplier & Time: Configurable startup delay and current parameters to accommodate initial motor inrush currents.
• Upper Electrode Waiting Time: The delay period after water touches the upper electrode before the pump restarts, ensuring the well has sufficiently replenished.
