A1 series rainproof three phase water pump controller adopts the original imported micrcomputer single chip technology,which has the advantage of powerful function and simple and convenient installation.The unique non-contact induction technology realizes the shutdown protection when the pump is dry run and short of water without installing a probe in deep wells.Make the pump truly realize full intelligent unmanned management.
Typical application scenarios:
-Agricultural irrigation/ pumping
-Pressure Booster Systems
-Waste water treatment
-Water Tanks/Wells
-Drainage System
-Cooling Towers
-Flood Control
-Fishing Boat
