Hello, I have bought an RD-6006P, that I have just received today. It is really a great PSU. But 2 problems: one is the breathing led when it is shutted down. And the other is a big one: it has overshooting problem :-[ :-\ FW version is 1.40, so coming already with latest version. Is someone has checked this ? Is my unit has any problem ? Maybe my simple setup to check this is not good ? I have also a DPS5005 which has not this problem at all. I have send a message to them on aliexpress with same photos (RD Official Store). Here are the screen from my new DSO: |

I don’t want to invest in buying another one. It is also time consuming. --- End quote --- Hello, So after my post, I have found and install your custom firmware, and I find it great, so thank you! :-+ I have read all the big "RD60xx Custom Firmware Reference.pdf" and have tried many settings. But I have the same overshooting problem with this one too, like the one I have posted before. After some searching, my thought is that it is probablly because the output is activated too fast. Do you think you could add a menu for slowing down the rise of ouput with a timing setting ? I have tried also the using of the green port with the GreenOutput option: it seems to be better, but randomly (I think the relay slows a little down the rise of the ouput). Also: same overshoot behavior after a releasing a short of the red/black bananas. Thank you ! 8) Edit: I have posted the video I have made for their support on Youtube: Edit2: Here is my 3 years-old DPS5005 in comparison (I have sent to the RD support). It is a lot slower, softer start, have more noise, but not a single overshoot. And I can not notice the slow start when I use it 8) |

That is a very bad news :-[ :-[ I have checked your schematics, it's the U8 part of the power part I think ? And the main firmware is in the U8 flash memory of the control part ? So I have to wait reply from RD... Also, maybe you could check if you have overshooting on your model too ? ??? It will be great to know that, I could then compare with mine (if there is a hardware problem on mine :-\ ) |
