Eaton SPI frequency drives are bi-directional DC power inverters for supplying and controlling AC motors. The inverter is supplied from a general DC bus drive. A charging circuit is needed if a live DC bus connection is required.
The SPI series inverters offer several benefits:
- Convenience of use
- Space-saving design
- Productivity
- Strong and safe
The DC side charging circuit supports up to 75 kW (for FR4 — FR8 frames) and uses external circuits for higher power ratings.
