Power Systems & Controls’ Series RFC is a Rotary Frequency Converter designed to provide equipment with 25Hz, 50Hz, 60Hz, 100Hz, or 400Hz power. The rotary frequency converter will meet the rated kVA requirements at the output with a high-efficiency motor and common shaft synchronous generator to yield the required frequency and voltage.  PS&C’s rotary frequency converters come in a 2 bearing or 4 bearing solution, as well as, vertical or horizontal configurations. A precision voltage regulator integrated within the system maintains the output voltage at (+/- .5%) far better than the industry standard.

Applications:

  • Aircraft Power
  • Weapons Systems
  • Manufacturing Facilities
  • Rail & Hydro Facilities
  • Sensitive Electronics
  • Test Lab & Research Centers
  • Process Automation Lines

Benefits:

  • 100% True Electrical Isolation
  • Precision Voltage Regulation
  • 2 & 4 Bearing M-G Sets
  • Control & Fault Monitoring
  • Transient & Brownout Protection
  • Vertical & Horizontal Configurations
  • Common & Single Shaft Designs

Under normal operation, the Series RFC acts as a rotating filter with the critical load being protected from utility transients and brownouts. The rotary frequency converter is available with either a synchronous or induction motor, whichever is best for the application. A synchronous motor creates an exact frequency output with no deviation, which is ideal for testing, flight, and weapon system applications. A low slip induction motor causes the output frequency to deviate (.6Hz), which is better suited for projects that require a more economical solution.

When operated at the rated motor speed, the frequency of the generator is controlled by the RPM of the motor, thus the output frequency can be variable. It is also 100% effective for outages lasting less than half a second. Also the absence of brushes and slip rings in both the motor and generator allows for virtually maintenance free operation. Furthermore, due to its rugged design the average end of life (EOL) of a rotary frequency converter is well over 20 years. There are also numerous options available ranging from remote controls and  color touch screen displays to specialized NEMA and ISO enclosures.
