This variable frequency water supply system is just for water pump, it adopts SPWM and pressure sensing technique, and it collects real time pressure change of the pipeline and adjusts the revolving speed of the pump.
Constant pressure water supply system makes the life comfortable, at the same time promotes life quality.
LCD screen display, the interface is easy to operate, no need of professionals to test or maintain.
Compared with the traditional water supply methods, variable speed drive water supply saves the energy up to 20%~60%, quite efficient.
Well-round protection for the pump to avoid unnecessary property damage.
Soft start and soft stop will make pump’s service life be longer.
Intuitive display makes it quick and easy to check and set real-time pressure values.
It is applied to a wide range voltage, especially in areas with large voltage fluctuation.
Easy installation, it can be used for different kinds of pumps, greatly save the cost.
