Question 1

In the diagram it shows only 2 wires for the input, are these the two hot (110) wires, if so where do I connect a neutral or ground?

Accepted Answer

Yes, the input is the 2 lines from a 220 breaker, so 2, 110v lines. I mounted mine in an enclosure with a nema l14-30 outlet. Neutral is not used, but I did run a ground to the standard ground prong of the l14-30 outlet, from the ground bar in my breaker panel. The ground is attached to the motor housing on the other end. With an l14-30 plug on my motor, I run my 3 phase drill press with an l14-30 extension cord. My l14-30 outlet has the 3 hots from the converter and ground, instead of the normal 2 hots, ground, and neutral.

Question 2

do you make one to be used on a 1/2 hp?

Accepted Answer

Dear customer,

Thank you for your kind question.

Yes, our 1HP phase converter could work to our 1/2HP AC motor.
And please refer to below information for using our phase converter.

1.	This item is worked at 1/2HP AC motor.
2.	The input/output voltage of our phase converter is 200v~240v.
3.	The voltage of motor should be 200v~240v. If the voltage of your motor is 380v or 440v, you have to change the motor wire to 200v~240v purpose to connect with output of our phase converter.
4.	This item should be used as one converter per one motor. Multiple motors are not allowed.
5.	The thickness of wires should be suitable for ampere.
6.	Only single phase motor brake is allowed.(Three phase motor brake is not working at our phase converter)
7.	You could check three phase on the output of phase converter when your motor is running.
8.	If your motor has magnetic starter, or electronic switch, or brake, the operating wires of this device should be connected on “U” and “W” of output of our phase converter. 
Thus, if your motor is not running well or the motor is reversing, you should turn off the power immediately and you have to switch the wires on output(U, V, W) of our phase converter. Actually, when you connect the wires from output of phase converter to your motor, you could succeed in first time, or second time, or third time.
9.	We will be appreciated if you could inform us what is horsepower(HP) and ampere of your motor and what kind of your machine. And then, we could give you our advice purpose to your convenience.

If you have other question, feel free to contact us anytime.

Best regards,

Mark Ko/Myung Youn Electronics Co.,Ltd.

Question 3

Hello, I would like to use 2 of these for synchronize testing to parallel. Just for bench testing other equipment. Can they adjust volts out ?

Accepted Answer

Dear customer,

Hello! Thank you for your kind inquiry.

Regarding your question, our DPS could be made 200V-240V 3 phase from 200V-240V single phase. Our DPS cannot change the voltage.
Our DPS is not a transformer. Your kind understanding would be appreicated.

Question 4

will a phase a matic run a  3 Ph miller wire wilder

Accepted Answer

Dear customer,

Thank you for your kind inquiry for our phase converter.
Our phase converter could be working your 3 phase motor from single phase. 
Could you please send us the nameplate of your motor? We could give us our advice after checking the specification of your motor.
Your kind reply would be appreciated.

Best regards,

Mark Ko/Myung Youn Electronics Co.,Ltd.
