    A single phase submersible pump control Panel will protect the submersible pump/motor from dry running, overloading with the use of micro controller. It must also show the voltmeter & current taken by the motor. Additionally, a timer facility is required, e.g. after electricity comes the motor should not start instantly, it should start after 3-4 minutes. PIC controller is more preferable.
