PS-WE63 controller is a pump set controller which is controlled by microcomputer with
automatic pressure tracking and regulating functions. The single-phase power gives it
a wide range of versatility in its application; the newly advanced control method of
adjusting power according water consumption can save a lot of electricity;the integrated
design makes it easy to be installed and operated without use of other appliance parts 
and be free of maintenance. It can entirely replace the traditional constant pressure water 
supply equipment composed by PLC, inverter, controller cabinet and pressure sensors. The
controller installed with two pumps will be the most economical water supply system
nowadays. As a result, this device can significantly reduce your initial equipment
investment and long-term use-cost.
