1140V Mechanical Medium Voltage AC VFD Drive for Blowers

Features

Benefits

Open Loop Vector and V/Hz Control with Torque Compensation

Provides excellent breakaway torque for thick materials and constant torque to maintain mixing speeds under heavy loads.

Preset frequency reference

Preset mixing patterns can be established for different materials.

Auto-Restart after momentary power loss

Mixing can quickly restart after fault or momentary power loss. This keeps perishable foods from spoiling in process.

Power loss Ride-Through

The mixing process in not interrupted during brief power loss (< 5 ms).
