Hi .. I'm new here and a complete beginner
I just have one simple question ..
Is there supposed to be continuity between
V1 (+5v ) and earth ground on the meanwell rd-35b psu ?
Any info would be great appreciated..
Please thanks

Re: Meanwell rd-35b simple question
On the PSU at my desk between V1 and Earth i have no continuity. Between V1 and COM yes. Do you have anything connected? Maybe something tying COM to Earth?

Thank you for yhe reply Mattwo...Mattwo_support wrote: ↑Mon Jul 08, 2024 10:36 am On the PSU at my desk between V1 and Earth i have no continuity. Between V1 and COM yes. Do you have anything connected? Maybe something tying COM to Earth?
Yes I have the whole system connected..
I used the schematic for multiple stepperonline CL86T... everything is wired up accordingly but motors not turning and I'm trouble shooting... noticed continuity where I thought there shouldn't be and thought I'd ask ..I ordered another meanwell rd-35b just incase mine is faulty
I will check tomorrow if something is tying com to Earth.. thank you again for your reply

Re: Meanwell rd-35b simple question
Test the Pinout of the supplied cables, I have had one case the colors mixed up.

Re: Meanwell rd-35b simple question
The supplied cables for my motors ?
Or the the supplied cables for the Meanwell rd-35b?

The ones for the Stepper...
... if they are mixed up on the stepper drive, the stepper will not run.

Re: Meanwell rd-35b simple question
Ok, I will double check all the wires

Re: Meanwell rd-35b simple question
I received my meanwell rd-35b pre-wired from centroidMattwo_support wrote: ↑Mon Jul 08, 2024 10:36 am On the PSU at my desk between V1 and Earth i have no continuity. Between V1 and COM yes. Do you have anything connected? Maybe something tying COM to Earth?
Com has a jumper to Earth ground..
So if on your bench test .. com and V1 have continuity .. then it would make sense why I have continuity between V1 and Earth..
Now my question is.. is my meanwell rd-35b pre-wired incorrectly??
I've attached pics .. what you see is how I received it..minus the wire on V1
Please advise
Thanks

Re: Meanwell rd-35b simple question
The wiring is ok. You can also see it in any schematics with the RD35B

Re: Meanwell rd-35b simple question
What does continuity mean? COM and earth are supposed to be connected and have very low resistance (<1ohm). With the power off and V1 disconnected, COM and V1 will show a high resistance (>1K ohm).
If you have low resistance (<1 ohm) between your disconnected V1 wire and COM you have a short in your wiring. If you have low resistance between COM and the V1 terminal when no wire is connected then you have a bad power supply.
What is the voltage between COM and V1 with the wire disconnected and the PSU powered?
