We offer a large selection of technology-leading phase converters. They operate with near unity power factor and essentially no harmonic distortion of the input while supplying balanced undistorted output voltage. It can safely power virtually any three-phase load within its rated capacity. Three-phase equipment such as submersible pumps, center-pivot irrigation systems, machine tools, sawmills, elevators, HVAC equipment, and CNC equipment are powered easily and reliably. Even when three-phase transmission lines are nearby, installing three-phase service is not cost-justified in many small to medium-sized applications. In these cases, we offer an affordable alternative source of three-phase power.

Static, rotary and VDF type phase converters are now available with voltage-doubling 240v to 480v capabilities. This compact frame size offers all of the advantages of an ATO smart phase converter in a NEMA 3R cabinet, that is compact, and offers the best value especially in 7.5hp, 10hp, 15hp, and 20hp.

Static Phase Converters

Static converters are generally recommended for constant load applications, like most fans or pumps, with one motor.

rotary phase converter

Rotary Phase Converters

Rotary type phase converters are usually recommended for the operation of a group of motors, or motors with considerable load variations.

single phase to three phase vfd

VFD Phase Converters

VFD phase converters are usually recommended for the operation of moderately-loaded 3-phase motors on single phase power .

digital phase converter

Digital Phase Converters

ATO’s digital phase converters are designed to provide precision three-phase power that will allow you to operate multiple loads simultaneously. Our digital phase converters are designed to power high inertia and high friction loads such as pumps, fans, and compressors while maintaining the balanced power necessary to run voltage-sensitive equipment like CNC machines.
