454GT LOW VOLTAGE DRIVES

The 454GT makes use of the latest IGBT technology: space vector modulation and surface mount construction to deliver benefits which save space, time and money.

This drive series utilizes advanced PWM (Pulse-Width Modulated) space vector technology, resulting in lower harmonics, smooth performance and extremely quiet motor operation. The unique application of the technology enables real-time waveform generation on a closed-loop basis, allowing the drive to automatically compensate for DC bus voltage changes in spite of line voltage variations. Space vector modulation actually "spreads out" sound energy over a wide range of frequencies, so motor noise is much less noticeable.
