Phase Technologies understands the impact of down-time in any pumping or irrigation application. Critical components are all field serviceable in the rare instance when the drive needs to be repaired on-site. Service Kits are available upon completion of Phase University Level 1 training.
Phase Technologies has designed a control system specifically to address the needs of center pivot irrigation. This variable frequency drive (VFD) provides full-featured speed control of the main pump and the optionally integrated AuxPower™ independently performs phase conversion and powers the pivot and it's control system.
Save time and frustration with a single solution designed specifically to handle the needs of your center pivot system.
Compared to a rotary phase converter, AuxPower™ can save hundreds of dollars per year in standby power consumption. The standby power usage of the modern solid state phase conversion technology in an AuxPower™ system is in the same ballpark as an incandescent light bulb, whereas many rotary phase converters can use more energy at idle than your household oven.

AuxPower by Phase Technologies is a unique, all-in-one solution that combines a Variable Frequency Drive (VFD) and a digital phase converter into a single, streamlined unit. Designed for locations where three-phase power isn’t available, AuxPower generates three-phase power from a single-phase source, while also offering full VFD functionality. It’s the ideal power solution for rural, remote, or retrofit applications where bringing in three-phase utility service is costly or simply not an option.
With AuxPower, you don’t need to purchase and install separate pieces of equipment. One unit handles both the conversion and control - saving time, reducing complexity, and simplifying installation. Whether you’re powering pumps, compressors, HVAC systems, or other industrial equipment, AuxPower delivers efficient and flexible performance in a compact footprint.
When you choose AuxPower, you're investing in more than just convenience, you're getting engineered performance backed by decades of innovation. Unlike traditional rotary phase converters or off-the-shelf VFDs, AuxPower is purpose-built for single-phase input and three-phase output, giving you clean, balanced power with precise motor control. This reduces mechanical wear, saves energy, and helps your equipment last longer.
Manufactured in the USA and supported by a team that understands your challenges, AuxPower delivers plug-and-play simplicity with industrial-grade reliability. It’s the smart choice for agriculture, manufacturing, and commercial customers who need robust performance without the hassle of piecing together multiple systems. If you’re looking for a dependable, all-in-one solution to convert power and control motors, AuxPower is the answer.
