⚙️ 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.
Advanced Low AC Voltage Sensing
Prevents electrode polarization in water using long-life stainless steel plastic molded conductive sensors that require zero frequent cleaning.
Comprehensive Visual Indications
Includes a 4-stage overhead tank level indicator, water flow indication, voltage level status, power ON, and auto/manual status indicators.
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.
3-Phase Voltage Cut-Off Range
Automatically cuts power if the supply voltage drops below 360V or crosses 500V AC across phases.
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.
