SEI VFD controllers are the ultimate solution to 3 phase electric motor control and this series is specifically designed to efficiently control pump motors. Smart period constant pressure adjustment in the water supply can set water supply pressure according to daily routines and automatically adjust the water supply pressure during peak/non-peak hours in order to save energy, reduce leakage and protect the pipeline. Eight periods can be set at most, with the longest cycle period being one week; a gradient adjustment function is also available.
