Intelligent Automated Operation: Enjoy seamless, hands-free pump control. Features Power On Auto Start functionality, an inbuilt Cyclic Timer for scheduled ON/OFF cycles, and a Borewell Recharge Timer to automatically restart the motor after the borewell water level recovers.
Programmable Cyclic Timer: The integrated cyclic timer enables you to define custom ON durations and OFF durations, automating the motor's operation cycle repeatedly based on your set timer preferences.
Automated Borewell Management: Combines dry run protection with smart restart; the unit stops the motor when water is depleted and uses the Borewell Recharge Timer to automatically resume pumping after a configured time for water level recovery. Detects water absence and stops the motor. Once the borewell recharges, it restarts the motor automatically.
Prevent Motor Burnout (Motor Overload Protection): Protects your motor with integrated motor overload protection. It automatically detects and stops the motor if it draws too much current, and you can precisely set the protection level according to motor's specifications. It is equipped with inbuilt Motor Overload Protection featuring user-adjustable settings.
Avoid Pump Seizure (Dry Run Protection): Protects your motor damage caused by running dry (without water). This automatically detects the dry run. You can adjust the dry run detection settings based on motor's specifications. 3 Phase Digital Auto Switch is equipped with inbuilt Dry Run Protection featuring user-adjustable settings.
Guard Against Power Fluctuations: Protects your motor from damage caused by unstable voltage supply. This device automatically shuts down the motor if the voltage goes above your set overvoltage threshold or drops below your set undervoltage threshold, ensuring safe operation during voltage swings. Integrated voltage protection device allowing you to define a precise safe operating range.
Real-Time Monitoring: Stay informed with the easy-to-read digital display. It provides instant visibility of key parameters like incoming Voltage, motor current draw (Amperes), active Timer information, and diagnostic Fault codes for quick status checks and troubleshooting. The integrated digital display clearly presents vital operational data, including real-time supply Voltage, motor Ampere consumption, Timer settings/status, and specific motor Fault indicators when issues occur.
Protection from Phase Loss Damage: Safeguards your valuable three-phase motor from severe damage or burnout caused by running on only two phases (single phasing). The integrated preventer instantly detects this condition and halts motor operation. An inbuilt single phase preventer that continuously monitors all three phases. If a phase loss is detected, it immediately stops the motor, providing critical protection.
Phase Order Detector: The phase sequence detector verifies the correct R, Y, B phase order and stops the motor if the sequence is wrong. 3 Phase Digital Auto Switch is equipped with an inbuilt phase sequence detector. It protects motor both during initial setup (if power cables are not connected properly) and during operation (if the phase sequence changes from the supply side).
Enhanced Safety and Durability: Incorporates a robust, inbuilt transformer coil. This critical component provides electrical isolation, separating the control unit from the main power feed. This significantly boosts operational safety, increases reliability (especially in areas with potential power fluctuations), and extends the overall life cycle of the auto switch.
Shock Proof Design: Engineered for safety, this unit features both transformer coil isolation (electrically separating circuits) and a durable, non-conductive high grade plastic enclosure to provide robust protection against electric shock hazards.
Connects to Your Existing Setup: This device easily attaches to the majority of three phase motor starter panels, whether it's a simple contactor panel, a standard panel with Green (On) & Red (Off) push buttons, or common starter types like DOL and Fully Automatic Star Delta used with openwell, monoblock, or borewell submersible pumps.

Operating Modes & Features
What are the different operating modes available on the Digital Auto Switch?
Our Digital Auto Switch offers three distinct operating modes to provide flexibility for various operational needs:
Auto Mode: This is the fully automated setting. In this mode, all programmed Timer functions (like Run Timer, Cyclic Timer, Auto Start Delay) are active, along with the complete set of built-in Motor Protection features (overload, dry run, voltage protection, etc.).
Manual Mode: This mode allows you to manually turn the motor ON and OFF using the device's controls, bypassing any programmed timer settings. However, all critical Motor Protection features remain active to safeguard your equipment.
Bypass Mode: Selecting this mode deactivates the internal controls (both timers and protection features) of the Digital Auto Switch. Your motor's operation will rely solely on your existing external setup.
What are the minimum and maximum durations I can set for the timers?
The Digital Auto Switch offers considerable flexibility in its timer settings. The maximum duration for functions like the Run Timer or the ON/OFF periods in Cyclic Mode can be configured for extended periods, typically up to approximately 40 hours.
Is the Digital Auto Switch difficult to program? What support is available if I need help?
We've designed the Digital Auto Switch to be user-friendly, even with its comprehensive features. Programming is typically done using intuitive onboard buttons and a clear digital display that guides you through the process.
To ensure a smooth experience and help you utilize all functionalities effectively, we offer dedicated support:
Bilingual User Manuals: You will receive detailed user manuals with step-by-step instructions, available in both English and Hindi.
Live Video Assistance: Should you require personal guidance during setup or programming, we provide live support via WhatsApp video call. Our technical team is available to assist you during standard working hours (typically Monday to Saturday, 10:00 AM to 6:00 PM IST, excluding public holidays).
Will the motor automatically restart when power returns after an outage?
Yes, the Digital Auto Switch includes an 'Auto Start' feature.
1 When enabled, it automatically restarts the motor once stable power is restored.
2 You can also configure an 'Auto Start Delay Timer' (user-settable) to introduce a brief pause before restarting, which helps protect the motor from potential power surges.
Can I set the motor to automatically switch OFF after running for a specific amount of time (e.g., 1 hour)
Absolutely. The unit features a programmable 'Run Timer'. Simply set your desired run duration, and the Digital Auto Switch will automatically turn the motor off once that time expires.
Is it possible to run the motor continuously?
Yes. If you don't require timed operation (like the Run Timer or Cyclic Timer), you can configure the Digital Auto Switch to allow continuous running whenever power is available and operating conditions are normal (e.g., no dry run detected). This mode typically involves disabling the timer functions as per the user manual instructions.
Can the Digital Auto Switch run the motor in cycles, for example: ON for 1 hour, then OFF for 2 hours, repeatedly?
Yes, the 'Cyclic Timer' function enables this.
You can program specific durations for both the ON (Run) period and the OFF (Rest) period. The switch will automatically cycle the motor based on these settings. This feature works alongside the dry-run protection; if a dry run is detected during an ON cycle (e.g., after 30 minutes of a 1-hour setting), the motor stops protectively and will wait for the programmed OFF period (allowing for borewell recharge, for instance) before starting the next cycle.
If a power failure occurs while the motor is running in a timed ON cycle, what happens when power resumes? Does it run for the full duration again or only the remaining time?
Our Digital Auto Switch provides both options via a configurable 'Timer Memory' setting:
Memory ON (Resume): The unit remembers the time elapsed before the power cut and will run only for the remaining duration of the ON cycle after power returns (following any Auto Start Delay). This is useful for precise water delivery needs.
Memory OFF (Restart): The unit will disregard the interrupted cycle and start a full, new ON cycle duration once power returns (following any Auto Start Delay).
You can choose the setting that best suits your operational requirements.
