Threephase frequency converter for 5A (3HP) 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 by moving 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.
