Phase Technologies’ DX Series 6-Pulse VFDs are an economical yet reliable option for speed control of three-phase AC motors. The drives offer advanced motor control features through an intuitive and easy to use interface.

Film bus capacitors eliminate the risk of catastrophic failure when starting a VFD after long periods without power. Unlike electrolytic bus capacitors, film bus capacitors do not degrade during storage. With DX Series VFDs the user eliminates the need for the added time and expense associated with reforming bus capacitors every season or when installing a VFD that was in storage for a very long period.

DX Series VFDs include an input reactor that is installed in front of the rectifier diode. The input reactor reduces harmonics on the input lines, protects the input stage from current surges, and reduces ripple on the DC bus. It also provides some protection against voltage transients, especially when an optional surge protective device (SPD) is installed.

The drive and enclosure are thermally engineered as one unit, directing airflow over critical heat-producing components while isolating sensitive components from outside ambient air. Unlike most outdoor 3R rated drives, the enclosure protects the electronics from dust and other contaminants while providing best in class cooling capabilities. This improves reliability and extends the expected lifetime of DX Series drives.
