Variable Frequency AC Source
Model : SOLID STATE FREQUENCY CONVERTER
Series : FRIVO
UDEYFRIVO series AC POWER SOURCES are solid state frequency converters offering the most costeffective and flexible way of providing dependable and accurate frequency and voltage conversion for low power singlephase applications.
Frequency converters are used to convert existing AC power supply into stable and pure sine wave power supply of required frequency. In UDEYFRIVO series this is achieved through AC – DC – AC conversion. Microprocessor is used as its heart with SPWM circuits, IGBT module adopting technologies such as ‘digital frequency division, D/A conversion, instantaneous feedback and Sinusoidal Pulse Width Modulation.
UDEYFRIVO easily converts mains 220V AC 50 Hz supply to Variable Output Frequency and Variable Output frequency as under:

0 – 150 – 300V 50 Hz

0 – 150 – 300V 60 Hz

0 – 150 – 300V 45 – 70 Hz

0 – 150 – 300V 100 Hz (Not available in FRIVO 53 and 55)

0 – 150 – 300V 200 Hz (Not available in FRIVO 53 and 55)

0 – 150 – 300V 400 Hz
Control is via front panel knobs.
