A well-known power electronics manufacturer VEICHI has adopted a new modern form factor for frequency converters – the “book” form factor. This includes series such as AC01, AC10, AC310, AC330, etc.
The dimensions of these inverters are optimal for cabinet selection, and the depth parameter does not create any issues. The parameters of these series are organized according to a unified principle – identical grouping and corresponding parameters under the same code.
If a setting is missing in a series, the parameter is simply skipped. This is a convenient concept since understanding one series makes it easy to work with others. When replacing series, parameters remain in the same locations.
Functional Features
- Built-in PLC for cyclic operation.
- Delayed start.
- Input logic inversion.
- Extended communication capabilities.
Control Panels
Three types of control panels have been developed for all series:
- Minimal with a single LED seven-segment display.
- Large with two LED displays and additional buttons.
- Large LCD display with extended functionality.
Control panels connect to the converter using a standard twisted pair and can be installed at significant distances.
Additional Features
- Support for additional modules: input-output, encoders, communication modules.
- Built-in EMC filters, braking modules, and DC chokes.
- Compliance with EU certification.
- High-temperature-resistant board coating similar to Schneider Electric.
- Compact and reliable housing with no unpleasant odors.
- Easy-to-replace 24V DC fan.
Thanks to modern IGBT modules, radiator size and overall device weight have been reduced. The protection system responds accurately to power outages and voltage fluctuations.
Conclusion
VEICHI frequency converters are reliable, high-quality, and affordable inverters suitable for a wide range of applications.
