AMTEX Electronics has announced the VFC500, a 500VA ac frequency converter, with variable frequency in the range of 47Hz and 424Hz, and output voltage continuously adjustable from 0 to 260V ac.
Housed in an 8.5" x 5.1" x 14" enclosed case, the VFC500 unit weighs nine pounds and is suitable for use in industrial and laboratory applications.
This includes simulating voltage and frequency deviations for equipment under development, verifying operation for export markets, and safety approval testing.
The VFC500 uses PWM technology to deliver a pure sine-wave output from any available ac line input: 115V ac at 400Hz, 120V ac at 60Hz or 240V ac at 50Hz.
Harmonic distortion of the output wave-shape is less than 5% at full load and frequency stability is ±0.1%. The output is fully isolated from the input and may either be used in floating mode or in grounded neutral operation.
The unit is fan-cooled and is rated for operation over a 0°C to 50°C temperature range. It features full electronic protection, is highly efficient and offers low output noise.
The VFC500 is designed to meet international safety approvals including IEC950, CSA22-2-950 and UL1950. Both ac input and output are highly filtered to meet the requirements for EN55022 Class B EMI emissions.
