Compact and lightweight, it delivers up to 90% efficiency while protecting against dust, moisture, and heat with its sealed design. Ideal for professional environments requiring reliable, energy-efficient motor operation from single-phase power sources. ## Description Before purchasing a DPS, be sure to check that the DPS model is compatible with your motor specifications. 1) DPS must be appropriately selected and used according to the motor specifications. Check the motor’s rated current (A), horsepower (HP), and voltage (V) and select the DPS model. 2) MY-PS-7.5 model should be used on 200V-240V 5HP 15amps 3-phase motor. If used on a motor with a horsepower lower than 5HP(for example 3HP, 2HP, 1HP motor), the motor may generate heat, make noise, and cause problems with motor operation. 3) DPS must be used for only one motor. One DPS should never be used on multiple motors. 4) DPS can make 200V-240V 3-phase from 200V-240V single-phase. 5) The voltage of the motor must be set to 200V-240V(Delta wiring-Low voltage). 6) The efficiency is around 90% when using a DPS model that meets the motor specifications. 7) The thickness of wires should be suitable for motor rated current. 8) DPS does not operate on 3-phase motor installed with 3-phase brake. 9) DPS creates induced three phases by running a motor. Therefore, three phases can be measured at the DPS output when the motor is running. If the motor is not running, you cannot measure any three phases at the DPS output. 10) If a magnet contactor is connected to the motor and DPS, you must connect two control wires which are from the magnetic contactor to 'U' and 'W' of the DPS output. If the motor does not work even though the power is turned on after connecting the DPS and the motor, please switch the wires positions of “U”, “V”, and “W” for DPS’s output at least 3 times. If the motor operates in reverse rotation and the positions of the 'U' and 'W' wires of the DPS output are swapped, the motor operates in forward rotation 11) If your machine has a magnetic contactor, it must be 220V only. DPS cannot work for a 380V or 440V magnetic contactor. 12) When the motor initially starts and there is not much load on the motor, the current on the 'U' and 'W' phases of the DPS output may become imbalanced. However, when more than 50% load is applied to the motor, the 'U' and 'W' current values are balanced. The 'V' phase is approximately equal to the motor's rated current value. 13) If the current is imbalanced even when the load on the motor is more than 50%, check whether the DPS model settings are correct. DPS has an available model depending on the specifications of each motor. If you use a DPS higher than the motor specifications, the motor may generate heat or noise. Also, please check whether the motor is overloaded. DPS efficiency is around 90%. In general, the three phases supplied by power companies and the three phases produced by DPS are different. This is because DPS converts from single-phase to three-phase. Therefore, please use a motor with an efficiency of 90% or less. Review: I purchased this unit to do a 3 phase conversion on a 5.3 HP CNC Spindle. My plan got changed so I really did not even use it or hook it up. The support from the seller was absolutely great. They were very helpful and insistent on ensuring you are ordering the right product immediately after your order is submitted. These units are for single driver only and each model is designed for a certain Horsepower rating. The Item came almost 3 weeks early from the estimated shipping duration. Review: Finally got around to installing this unit on my 5hp 3 phase table saw. Seemed to work okay for the first few days. Then it would surge a couple times on start up before holding and working okay. Last night after running for maybe two hours off and on, the amperage limit tripped on the saws magnetic switch. Reset it and tried again and it started up and ran, but it sounded kinda weird, looked down and saw smoke pouring out of the DPS unit. Really sucks that I internationally bought a unit rated for 7.5hp to run a 5hp saw, just as I was advised, and felt good thinking I had plenty of overhead before I would overwhelm the unit. Smoked and fried in the first week. And no way to contact the seller through desertcart because I didn’t get around to setting it up for a few months and now I am out of the return policy time. Waste of money. ## Features - DPS can run 3-phase motor with single-phase - Very easy to connect DPS and motor - Small size & light weight - Doesn’t make any high frequency/Lower power consumption - Keeps out dust, moisture, and heat due to the sealed type ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F243HLG | | Item model number | MY-PS-7.5 | | Manufacturer | DPS | | Product Dimensions | 12.5 x 10 x 18.5 cm; 1.14 kg | ## Images ![DPS Capacity 7.5HP 23A 220V, Single Phase to Three Phase Converter, MY-PS-7.5 Should be Used for 5CV(3.7kW) 15A 220V Three-Phase Motor Only, Must be Used For One Motor Only, UL Listed - Image 1](https://m.media-amazon.com/images/I/61CY8h2ZEoL.jpg) ## Questions & Answers **Q: The motor runs fine with the DPS connected, then suddenly stops running.** A: Check to see if the motor is overloaded. The motor should be at 90% load or less. Also, make sure that the DPS model matches the motor capacity. It is possible that the DPS components are damaged due to overcurrent. **Q: The motor runs with the DPS connected, but the power is weak.** A: Make sure the input voltage and wattage are normal and check the motor load. Also, make sure that the DPS model matches the motor capacity. **Q: The motor slows down and does not run smoothly.** A: Please check the motor load and use it with a load condition of 90% or less (overcurrent phenomenon due to overload). **Q: The output current and voltage of the motor is too high, causing overheating and noise.** A: Make sure that the DPS model is correctly selected for the motor capacity. This is caused by using a DPS with a capacity that is too high for the motor capacity. Also, check if the motor is overloaded. **Q: Can the DPS be used with heaters, ovens, or sunbeds?** A: For heating equipment such as ovens, DPS operates at an efficiency of approximately 70%, which is lower than the standard 90% efficiency. Lower efficiency may result in extended heating time compared to normal operation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***T on 27 February 2021* I purchased this unit to do a 3 phase conversion on a 5.3 HP CNC Spindle.
