Eaton SPI frequency drives are bi-directional DC power inverters for supplying and controlling AC motors. The inverter is powered by a general DC bus drive. A charging circuit is required when a live DC bus link is needed under load. This type of frequency drive offers several advantages:
- Ease of use
- Compact construction
- Economy
- Robust and safe
The DC side charging circuit supports up to 75 kW and uses external circuits for higher power ratings.
