Power Systems & Controls’ Series SFC-3 is a Static Frequency Converter designed to provide equipment with 25Hz, 50Hz, 60Hz, 100Hz, or 400Hz power. The three phase static frequency converter converts the source power of one voltage and frequency to the voltage and frequency required. Solid-state technology means that the static converter’s only moving parts are the fans used for forcing cooling the system. PS&C’s solid-state converters are built upon a dynamic platform, and incorporate the latest technology in solid-state PWM inverter and rectifier controls.

The PS&C Series SFC utilizes 6 and 12 pulse, as well as, “IGBT” topology for the most efficient solid state frequency conversion available. This advancement in digital technology gives PS&C’s converters a great advantage over other conventional converters. Although IGBT’s are a more expensive solution, PS&C has avoided utilizing older technology to provide a product with an incredible input allowing this machine to support equipment in the most extreme electrical conditions.

You will be satisfied whether you opt for the IGBT/IGBT topology with THD less than 1%, efficiency up to 97%, and input power factor at .99 minimum or the standard SCR/IGBT built systems as we have been designing solid-state frequency conversion systems for decades. PS&C’s static frequency converter is available from 10 – 2,000kVA, and is ideal for applications where footprint, noise, and controls are a priority. There are also numerous options available ranging from a color touch screen display and advanced communications to specialized NEMA and ISO enclosures.
