Signature Series VFD's
DX Signature and Performance Chassis

Commercial and Agriculture AFE VFD

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.

See the DX Enterprise for applications requiring less than 20 horsepower or 230 V output.

Options

MCCB & Service Rated Disconnect

An external service disconnect and integral breaker for ease of maintenance or installations that require it to meet electrical code.

Surge Protection

Available factory-installed surge protection options include ProTec, single event MOV type, as well as Strikesorb. Strikesorb provides class-leading multiple hit protection ensuring continuous protection of your critical equipment.

Output Filter

460 V installations other than those with short lead lengths often require output filtering to protect the motor from damage.

Hand/Off/Auto (HOA) Switch with Speed Potentiometer

Externally mounted HOA switch and speed potentiometer. Used to switch between user or automatic control and adjust motor speed on the output of the drive.

AuxPower

Drive your pivot with the same solution used to control your pump using optional AuxPower, available on drives configured with a Performance Series chassis.

Extended Warranty

Although durable and robust in design, a little extra peace of mind never hurts. Phase Technologies is happy to offer an extended warranty for all of those applications that demand a bit extra.
