Variable Frequency AC Source

Variable Frequency AC Source

Model : SOLID STATE FREQUENCY CONVERTER

Series : FRIVO

UDEY-FRIVO series AC POWER SOURCES are solid state frequency converters offering the most cost-effective and flexible way of providing dependable and accurate frequency and voltage conversion for low power single-phase applications.

Frequency converters are used to convert existing AC power supply into stable and pure sine wave power supply of required frequency. In UDEY-FRIVO 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.

UDEY-FRIVO 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.
