Customer Benefit
- Highly reliable operation, expected 20-year drive MTBF
- Considerable energy savings
- Capacitors not required for power factor correction
- No harmonic filter required to provide lower harmonic distortion levels than IEEE-519-1992 guidelines
- No output transformer required, saving cost, mounting space, and energy
Suitable for standard motors due to motor friendly wave form
- Allows starting control of multiple motors with one drive
- No motor current or torque transients when the motor transitions to the AC line
- Less power loss in drive room
- Less total space required
- Simplifies design and installation
