I have a 10 HP -230 volt 3 phase hydraulic press brake. I just installed a new 40 HP rotary converter panel with used WEG motor. The problem i am having is the volts going into the press during a load is dropping from 245 to 195-200 volt. Which means i'm loosing power of the hydraulic system. Wonder if anyone has a idea of what could be causing this. The required rotary converter is a 30HP and i went to a 40HP just to make sure.
