With the development of science and technology, irrigation has become more and more intelligent, especially the use of submersible pump controller, to give the farmers a great convenience. Submersible pump controller is determined by the transmitter and receiver of two parts, the submersible pump submersible pump controller and the receiver are connected together, submersible pumps emitter on the operator who, regardless of the operating personnel in the license at any time in any place You can power on their own, very convenient. Submersible pump submersible pump controller, also known as remote control, remote control switch submersible pump, submersible pump protection, essentially is a combat submersible pumps, three-phase motors and other electrical equipment in case of operation phase burned remote control device, is a combination of power control technology and wireless communication technology water controller, through wireless control means to achieve remote control processing of submersible pumps. It can be widely used in submersible pumps, mud pumps, rolling machines, deep well pump, three-phase electric motors and other long-distance remote control. Good quality submersible pump controller transmit power, receive sensitivity, Kongkuo zone remote control in about 1700 meters, so that can save people commute elbow grease, saving time and effort. Submersible pump controller also has a main power phase automatic power-off function, can effectively prevent the submersible pump body, three-phase motors and other electrical equipment in case of operation phase and burned, greatly reducing the farmers in the submersible pump pump on investment. The use of submersible pump controller, effectively improve the efficiency of field operations of farmers and enthusiasm, had more than one person to complete irrigation effortlessly becomes a person will be able to easily accomplish. General submersible pump controller can be widely used in various connections have three-phase motors electrical equipment. Has good power phase protection, overload protection, overvoltage protection. However, factory production of submersible pump controller does not have leakage protection and should be used with leakage protection, knife and other ancillary uses.
