Product features
1. This VF constant pressure water supply system is for pump use only, it adopts industry SPWM (Sinusoidal Pulse Width Modulation) technique, together with pressure sensing technique, it collects real time pressure change of the pipeline and adjusts revolving speed of the pump.2. Easy to operate with an easy-to-use interface, no need of professionals to test or maintain.3. Compared with the old water supply methods, VF constant pressure water supply saves the energy up to 20%~60%, quite efficient.4. Constant pressure water supply pressure makes water-using enjoyable, as well promotes life quality.5. Soft start and soft stop makes pump's life span longer.6. It fits to wide voltage range, especially in areas with large voltage fluctuation.7. Overall protection over pumps keeps unnecessary property loss away.8. Easy installation to various kinds of pumps cuts your cost greatly.9. Direct display makes checking and setting real time pressure quick and easy.
