產品描述
Feature:特性
1. This VF constant pressure water supply system is for pump use only, it adopts industry-leading SPWM (Sinusoidal Pulse Width Modulation) technique, together with the advanced pressure sensing technique, it collects real time pressure change of the pipeline and adjusts revolving speed of the pump.
此變頻恒壓供水系統僅供水泵使用，采用了行業的SPWM技術，先進的壓力感應技術，采集管道實時壓力變化并對水泵轉速進行調整。
2.Easy to operate with an easy-to-use interface, no need of professionals to test or maintain.
界面簡單易操作，無須人士進行測試或維護。
3.Compared with the old water supply methods, VF constant pressure water supply saves the energy up to 20%~60%, quite efficient.
和以往的供水方式進行比較，變頻恒壓供水節約的能源高達20~60%，十分。
4.Constant pressure water supply pressure makes water-using enjoyable, as well promotes life quality.
恒壓供水使用水變得享受化，同時提高生活品質。
5.Soft start and soft stop makes pump’s life span longer.
軟啟動軟停機增長水泵使用壽命
