M-POWER PRO is a module designed for a mobile starter. It combines two very important functions: Remote Operation (On/Off) of the pump through mobile and protection from dry run fault.

It is designed to work with any starter/controller and is convenient to install and use. Using mobile phone, farmers can monitor important parameters such as voltage, current, motor run time, motor status (On/Off), etc. They can also change the settings of overvoltage (O/V), under-voltage (U/V) and dry run protection (DRP) with ease through their mobile phone.


  • Enables the operation (Remote ON/OFF, parameter setting, monitoring and troubleshooting) of your pump through SMS, IVRS, Call and LTLK Connect Android app, thus provides the convenience in controlling the pump operation from anywhere at anytime
  • Only 3 wire connection ensures easy installation with DOL and Star Delta starters
  • Offers protection from phase loss, voltage unbalance, phase reversal, over-voltage, under-voltage and the dry run fault with individual protection Enable/Disable feature.
  • The same unit works for Three Phase DOL and Star Delta starter
  • Hour based and Network-based daily timers (4 Time slot) with time compensation
  • Up to 4 users along with 1 master can be connected for controlling your pump operation
  • Auto/Manual/Bypass mode and total run time information for your pump

Smart Controller (DOL Version):

Smart Controller is the all in one digital controller which combines the traditional function of a controller, remote switching capabilities of M-POWER PRO, short circuit protection features of MCB, dry run protection features of i-PROTECTOR and an additional feature known as anti-theft which not only protects the motor but also cable and controllers against theft.

It offers every essential feature that makes your life convenient and farming efficient.

Range: Up to 10 HP


  • In-built anti-theft protection gives an emergency alert to your mobile when someone tries to steal your pump, cable, or controller
  • Comes with Dry Run, Locked Rotor and Short Circuit protection (Inbuilt LTLK MCB)
  • Voltage and current based protection for all faults with individual protection Enable/Disable feature
  • Inbuilt hour based and Real-Time Clock based timers with time compensation feature
