SC9000 EP variable frequency drive (VFD) Frame F is designed for use with 4160 V induction or synchronous motors from 6500 horsepower (Hp) up to 12000 Hp. Built on the SC9000 EP platform, the Frame F includes silicone encapsulated powerpole to yields a high reliability, even in severe environments such as wastewater, mining and oil & gas. Additionally, the Frame F drive uses proven SC9000 EP components including rectifiers, inverters and dV/dT filters connected in parallel to achieve ratings up to 12000 Hp.
