Sri DIGITEK® Dual Motor Automatic Water Level Controller
Specially designed for dual motor operations, the ULDX-ACH-MSS-03 controls one sump motor and one borewell motor feeding into a common overhead tank[cite: 8]. Featuring intelligent Sump Mode and Borewell Mode automatic switching, it ensures uninterrupted water management with robust industrial-grade protection[cite: 8].
⚙️ Key Features & Engineered Advantages
Dual Motor Sump & Borewell Operation
Designed to control one sump motor and one borewell motor pumping to a single common overhead tank[cite: 8].
Intelligent Mode Switchover
Operates on Sump Mode when water is available; when sump water drops below the foot valve level, it automatically switches over to Borewell Mode, resuming Sump Mode once the sump refills[cite: 8].
3-Position Pump Selector Switch
Features a physical selector switch for Auto, Pump 1, or Pump 2 operation. In Auto, both run automatically; selecting an individual pump isolates the other[cite: 8].
Advanced AC Sensing Technology
Software-driven AC sensing eliminates electrode polarization in water, paired with stainless steel molded conductive electrodes lasting up to 10 years[cite: 8].
Dry-Run & Voltage Protection
Includes dry-run detection with a 120-second delay, automatic voltage cut-off below 170V or above 270V AC (single phase / 360V-480V 3-phase), and built-in surge protection[cite: 8].
Manual, NEED & Bypass Switches
Includes Auto/Manual soft switch for utility tasks, an optional NEED switch to force-start irrespective of tank levels, and a Rocker Bypass Switch for failure overrides[cite: 8].
