Eaton SPI frequency converters are two-forked DC power inverters for supplying and control of AC motors. The products are powered by a general DC bus drive. The charging circuit is required in the event that a live DC bus joint is needed. The SPI series inverters have many advantages:

• Ease of use
• Space-saving construction
• Productivity
• Rugged and reliable

DC side charging circuit integrated up to 75 kW and external for higher output ratings (FI9 - FI14).
