[CC] DPS Digital Phase Shifter in a Demo Board & Testing with a Hioki CM3286-01

Hi guys! In this video I installed a DPS, Digital Phase Shifter on a Do-It-Yourself demo board that I made, and tested it with a Hioki CM3286-01 AC Clamp Power Meter. The DPS is a single-phase to three-phase converter. It allows you to run a 3-phase motor out of the available single-phase power supply. The DPS unit model is an MY-PS-2, rated for 1Hp, 220V 3-phase, which is a match for my 1Hp, 3-phase Meiji induction motor. The objective of installing the DPS on a demo board was for me to have 3-phase voltage available for testing purposes, not necessarily for motor control. The DPS did output 3-phase voltage, but it has certain limitations which I discussed in the video. I provided timestamps for easy navigation to topics/chapters. The DPS device is made in Korea.

Hi sir, how about the current output of the motor? Tama po ba sa rating while running? Thanks

Excellent is precisely the information I was looking for, I congratulate you for your work!! Greetings from Mexico

Thank you for the video, I have a question for you. With no motor hooked up the DPS outputs single phase, two wires have power going out. When a 3 phase motor is powered on single phase, 2 wires having power to it, the third wire on the motor will output power ( like a motor for a rotary phase converter ). When you checked voltage with the motor running how do you know the DPS was putting out 3 lines of power? Couldn't it still be putting out single phase ( two lines ) and the third line was incoming power from the motor that showed your voltage reading?

Thank you very much for the information, I thought about buying the equipment to test frequency converters in my laboratory but it will definitely not help me, a great contribution, greetings from Peru

After two years, would you still recommend this unit? I contacted the company through ebay regarding my 1.5 hp motor and they were less than helpful regarding whether this unit would work or not. I was quite disappointed. But I don't want to damage my motor. Thank you.

Ram, have you tried other similar products that have less imbalance?

[alexeydearanaespinosa]

Hi, thanks for you video...i have one question ? Do you know if this DPS can work with 2 phases 110 volt as in america Dont have one single fase 220 as europ

[vivekkumar-hpyq]

great review. I believe that there is only one capacitor placed inside the phase shifter.

[tomsuica]

I love how you bend your wires. Some of them may be bent past the maximum bend radius though.

Hello! Excellent video! Question. Will this Digital Phase Shifter work for an industrial fan application with a 1hp 3-Phase motor? My concern is if the fan blades would provide enough load to balance the voltages across the legs, since they're not balanced when the motor is unloaded. The blade on this fan is about 30 inches diameter. Would you recommend this for a fan application?

As usual to every uploaded videos sir Ram, very informative content to sir! Looking forward to see more videos from your channel 😀

[reneacobausa]

good morning sir i like how you explain on your demo very clear and i understand good job.

[mystified]

Great review. Nice work, I appreciate the detail. Thanks

[mkacytchannel]

Hello sir is it applicable to PMSM motor 3 phase .38 HP

[reylyndaggao]

hi siir! my question is, is it posible to use this device (DPS) for aircon 5TR? thanks for your answere? Godbless

[MrVozka]

Anyone running a 7.5 hp compressor with this

[cartvincentpalaypayon]

Can I use that on forward reverse control And wye delta control?

[adambergmann]

can this be used to run a vfd that will run the motor?

[BloodCover]

Are both wires on the top of the phase shifter hot wires 120v each or is one a ground wire

Hello, I have DPS and it does the same as your test shows on the voltage imbalance…. I am disappointed however in my unit… it claims to have excellent start up torque….But it won’t start my machine unless it is in low speeds. It doesnt seem to have good start up torque as claimed. I run a 3 hp motor on a milling machine. I have to start it in low speed 1st and once running then I can turn my variable hand crank to maximum speed. It makes it difficult if I forget to turn it back to low speed before shutting machine off because machine needs to be running to change speeds. My speed change is done via 2 pulleys opening/closing while running only.
