WSS INVERTER MZC series AC VFD
WSS INVERTER MZC series Special for Multi-pumps Water Supply
Features and advantage
MZC series is adopts the advanced control theory to adjust speed and switch over of pumps automatically according to the pressure of pipe net, so as to make the water pressure to be constant. It can control up to 4 water pumps
Power range
380V ±15%; 5,5~250kW
