\nDry run protection with sensor free, single phase pump controller for borehole pumps<\/strong><\/span><\/p>\n

S521 is a single phase pump control panel which supports dry run protection with sensor free. It saves cost and labor for users,especially for borehole pumps which is difficult to install sensors in the deep well. As S521 has push button calibration function. The rated\u00a0ampere can be memorized into the control panel by pressing STORE button inside the control. When the running\u00a0ampere drops to 70% of the rated current, control panel will regard it as dry run and stop the pump.<\/strong><\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
