Overview

Designed for workshops and industrial facilities, the 3kW single phase to three phase power converter converts single-phase input into high-quality three-phase output for motor-driven loads. The unit features pure sine wave power, high efficiency up to 94%, and stable frequency output, ensuring reliable performance for industrial motors, CNC machines, and mechanical equipment. It provides an efficient way to operate three-phase machines using single-phase electricity without installing expensive three-phase power lines.

Note:

When the load is a motor, the phase converter should be more than 5~7 times the motor capacity.
When the load is soft start + motor, the phase converter should be more than 3 times the motor capacity.
When the load is VFD + motor, the phase converter should be more than 1.5~2 times the motor capacity.

FAQ

Q1: What motor size can a 3kW single phase to three phase converter run?

A 3kW phase converter is typically suitable for motors up to about 3kW (around 4HP). It provides stable three-phase output for small machines such as drill presses, small lathes, and cutting machines.

Q2: Can a 1 phase to 3 phase converter run multiple machines?

Yes, a single phase to three phase converter can power multiple machines if the total power consumption does not exceed the converter’s rated capacity. It is commonly used in workshops and factories where several three-phase motors or machines need to operate from a single-phase power supply.
