The SPI series frequency drives are two-forked DC power inverters for supply and control of AC engines. This inverter is supplied from a common DC bus. A charging circuit is needed in case a live DC bus link is required. The SPI types inverters have many benefits:

• User friendliness
• Compact design
• Productivity
• Robust and safe

Eaton DC side charging circuit has up to 75 kW and outer for higher rated output.
