DXE Signature Series VFD’s are designed with film bus technology to ensure little to no down time when commissioning the system at the beginning of each season. By utilizing the latest advances in power electronic and capacitor technology Phase Technologies VFD’s are the best choice for motor control applications. The DXE Series is designed with class leading field serviceability.

The drive and enclosure are thermally engineered as one unit, directing air flow over critical heat-producing components while isolating sensitive components from outside ambient air. Most outdoor 3R rated drives integrate a NEMA 1 indoor VFD in an outdoor enclosure without segregating the airflow. The drive and other sensitive components can be degraded due to re-circulated hot air and contaminants from the outside air.
