AC/AC Frequency Converters 500W with Variable Output Frequency 40 – 410Hz

The VFC500 series Frequency Converters are designed for in Laboratory and many R&D applications, where there is a requirement for a variable output frequency. The output volatge is also variable over the range 0 – 264VAC. The output frequency can be adjusted by ‘Hot Push Buttons’ in steps of 50, 100, 200 and 400Hz, plus further adjustment to set to required frequency range. There are two mechanical styles, the standard bench mount unit and a rack mount style.
