Sri DIGITEK® Three Phase Submersible & Borewell Controller
The Sri Digitek ULDX-DR-3PH is a specialized submersible pump controller and panel driver engineered specifically for 3-phase run motors[cite: 3]. Built with high reliability and low maintenance, this unique device maximizes motor lifespan across heavy-duty commercial and agricultural borewell applications[cite: 3].
⚙️ Key Features & Engineered Advantages
3-Phase Submersible Panel Driver
Designed as a unique device optimized for 3-phase run submersible motors to enhance operational longevity[cite: 3].
Advanced Low AC Voltage Sensing
Prevents electrode polarization in water using long-life stainless steel plastic molded conductive sensors that require zero frequent cleaning[cite: 3].
Comprehensive Visual Indications
Includes a 4-stage overhead tank level indicator, water flow indication, voltage level status, power ON, and auto/manual status indicators[cite: 3].
Dry-Run & Low Source Protection
Automatically shuts off the motor and signals a fault if running dry due to faulty foot valves, pipe air leaks, or low water sources[cite: 3].
3-Phase Voltage Cut-Off Range
Automatically cuts power if the supply voltage drops below 360V or crosses 500V AC across phases[cite: 3].
Soft Switches, NEED & Bypass Controls
Features Auto/Manual mode for utility tasks, an optional NEED switch to force-start regardless of water levels, and a Rocker Bypass Switch for failure overrides[cite: 3].
