Three-phase frequency converter for 14 A (7.5 HP) electric pump. The power supply is 400v. It can be mounted individually or in group by 2, 3 or 4 pumps, communicating with the control center alternating the operating sequences. One or two converters can work directly with a pump, but when 3 or 4 inverters come in, a command center is required.
