Warranty

 

American DPS products are covered by a one-year warranty from the date of purchase for failures that occur during normal use.

However, warranty coverage does not apply to failures or damage caused by customer negligence, misuse, improper installation, or natural disasters. In such cases, repair or replacement may be subject to charges, and all related shipping costs are the customer’s responsibility.

How a Single Phase to
3 Phase Converter Works (DPS Guide)

DPS is designed to operate a three-phase motor using single-phase 200–240 V power.

Unlike a standard three-phase power supply, DPS works together with the connected motor. When the motor starts and runs, DPS generates the required phase-shifted output and allows the motor to operate as a three-phase motor.

Because DPS creates the three-phase output while the motor is running, three-phase voltage can be measured at the DPS output only when the motor is operating. If the motor is not running, three-phase voltage may not be properly measured at the DPS output.

For this reason, DPS should always be checked under actual motor-running conditions, not by measuring the output with no motor load connected.

Due to this operating characteristic, the output voltage on each phase may not show exactly 220 V, and the measured values may be different from each other. This is normal for DPS operation. As the motor load increases to 50% or more of its rated load, the output becomes more balanced. Lower voltage readings tend to rise, while readings that appear high may settle into a more appropriate range.

The operating efficiency of DPS is approximately 90% based on the motor nameplate rating. Since DPS converts single-phase power for use with a three-phase motor, it cannot provide 100% efficiency or support a load higher than the rated motor capacity.

Who needs DPS?

For users who have only single-phase 200–240 V power available but need to operate a three-phase 200–240 V motor, DPS provides a practical solution without requiring three-phase utility power installation.

Applications
That Work with DPS

DPS can be used for many single-motor applications, including pumps, fans, blowers, compressors, food processors, woodworking machines, agricultural equipment, and other machines powered by one three-phase motor.

For applications such as lifts, hoists, or heavy-starting equipment, please contact us before choosing a DPS model to confirm compatibility.

How to Choose
the Right DPS Model

First, check whether your machine is a single-motor application. One DPS should be dedicated to one three-phase motor. DPS is not designed to operate multiple motors with one unit.

Choose the DPS model based on the motor horsepower, amperage, voltage, load condition, and application type. For stable operation, the motor should generally operate at 50% or more of its rated load.

The recommended motor capacity table below can help you select the proper DPS model for your application.
