Description
The MicroMagic Dry Run DAS7272 Auto Switch is an advanced, microcontroller-based protection device engineered specifically for 3-phase water pumps. Capable of driving Direct Online (DOL) starters for pumps ranging from 1 HP up to 7.5 HP at operating voltages up to 440V AC, it features a clear digital display for real-time voltage and current monitoring. The intelligent controller automatically restarts the motor upon power restoration while continuously safeguarding it against dry running, single-phasing, and severe high/low voltage fluctuations. Built to endure volatile electrical conditions, it extends motor lifespan and reduces downtime across agricultural, commercial, and residential pumping setups.
Features
:- Voltage & Current Digital Display: Features integrated digital metering to provide real-time monitoring of system voltage and motor load current.
- Advanced Microcontroller Control: Uses intelligent digital processing for precise fault detection, automated restarts, and reliable motor management.
- Intelligent Dry Run & Phase Protection: Prevents motor burnouts by cutting power during dry running, single-phasing, or voltage irregularities.
- Heavy-Duty Relay Integration: Incorporates a heavy-duty industrial relay engineered for DOL starter setups from 1 HP to 7.5 HP.
- Dual Auto/Manual Operation: Offers flexible control options with an easily accessible Auto/Manual toggle mode.
Applications
:- Borewell & Submersible Pumps: Preventing deep-well motor burnouts caused by dry running, low voltage, or phase loss.
- Agricultural Irrigation: Automated crop watering control and motor protection for farm pumps.
- Openwell Water Systems: Monitoring and controlling openwell agricultural and residential pump installations.
- Commercial & Residential Buildings: Automating water transfer setups in high-rise complexes and commercial spaces.
Usage
:- Mount the MicroMagic DAS7272 unit vertically and securely onto a wall surface adjacent to your DOL starter panel.
- Ensure the main 3-phase power supply is completely switched off before making any electrical connections.
- Wire the 440V AC supply lines and starter control leads into the unit according to the included circuit diagram.
- Select your preferred operational mode using the Auto/Manual control switch.
- Switch on the primary power supply; observe the digital display to verify live voltage and current readings.
- The system will automatically manage motor start/stop cycles while continuously protecting against dry run or phase failure faults.
