Sri DIGITEK® Ultra Deluxe Automatic Water Level Controller
The Sri Digitek™ ULDX-HA-02 is a high-performance, compact system built with industrial-grade components[cite: 1]. It operates on a single-chip micro-controller, running on software with sleep-mode capability to consume minimal power[cite: 1]. Equipped with a built-in 40-amp power relay, it offers advanced automation, surge protection, and maintenance-free operation[cite: 1].
⚙️ Key Features & Engineered Advantages
Advanced AC Sensing Technology
Software-driven AC sensing avoids electrode polarization in water. Uses special-grade stainless steel moulded conductive electrodes that are long-lasting and maintenance-free[cite: 1].
Extra Water Storage Logic
Whenever water reaches 100% in the sump tank, it switches ON the pump to fill the overhead tank (if overhead tank water is above 50%), ensuring extra storage in the sump[cite: 1].
Comprehensive Visual Indications
Features 4-stage level indication for overhead tank, 3-stage for sump, plus water flow, voltage level, power-on, and auto/manual status indicators[cite: 1].
Dry-Run Protection
Automatically shuts off the pump and provides fault indication if the motor runs dry due to faulty foot valves or pipe air leaks (120 seconds delay)[cite: 1].
Built-In Voltage & Surge Protection
Automatically switches off the pump if supply voltage drops below 170V AC or crosses 270V AC (single phase), paired with built-in surge protection[cite: 1].
Manual, NEED & Bypass Controls
Includes Auto/Manual soft switch for direct drawing (car/area wash), an optional NEED switch to force-start regardless of tank levels, and a Rocker Bypass Switch[cite: 1].
