The Eaton SPI variable frequency drives are bi-directional DC power inverters for supply and monitoring AC motors. The inverter is powered by a common DC bus drive. The charging circuit is required in the event that a live DC bus connection is essential.
This type frequency converter has many benefits:

• User friendliness
• Space-saving design
• Economy
• Robust and safe

Eaton DC side charging circuit has up to 75 kW (FR4 - FR8) and external for higher power ratings (FI9 - FI14).
