Udey Variable Frequency AC Source Udey Test Kits

Model : SOLID STATE FREQUENCY CONVERTER, VARIABLE FREQUENCY AC SOURCE

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:

1. 0 – 150 – 300V 50 Hz
2. 0 – 150 – 300V 60 Hz
3. 0 – 150 – 300V 45 – 70 Hz
4. 0 – 150 – 300V 100 Hz (Not available in FRIVO 53 and 55)
5. 0 – 150 – 300V 200 Hz (Not available in FRIVO 53 and 55)
6. 0 – 150 – 300V 400 Hz

Control is via front panel knobs.

Simplicity in operation:

Plug and socket connections with few knobs mean minimal operator training. LED digital displays for output – Frequency, Voltage, Current, Power and Power Factor.

Protection for ‘Short-circuit’, ‘Over-current’, ‘Over-load’ and ‘Over-heat’ is provided to ensure proper operation with audio alarm.

UDEY-FRIVO is built in single unit sheet steel cabinets. Output is available on 3-pin sockets for connecting the load. The power supply is very compact and low in weight.

Applications:

UDEY- FRIVO series are suitable for applications ranging from production-line testing through to research and development laboratories, workshops, shipyard, ship manufacturing and repair plants, etc.
