In my recent quest to research the current programmable linear power supply offerings of the holiday season, I ran into this... https://www.amazon.com/Programmable-MPS-3033X-Adjustable-regulated-Resolution/dp/B08W28FF9D Retailing on Amazon for $399 (currently has a 25% off coupon code for ~$100 off = $299!) is a Matrix brand programmable PSU. Its clearly a knockoff BK Precision with specs that align to the 9130b model. It has three fully isolated channels (x2 0-30V@3A, x1 0-6V@3A), 1mv/1mA resolution, serial/parallel/track modes, sense inputs in the back as well as RS-232 and USB, etc. Its got a single rating for 2-stars with no explanation. Oh, did I mention its $299 with coupon code!?

For the price (and free returns) I decided to give it a go and rolled the dice. Anyone have any experience with this model or one similar?? |

I don't think that is an isolated supply. I can find no mention of it in the specs, but I might have missed something. |

Hi, yes, three channels are isolated |
| fyl2022:
you can go to their youtube channel to get more information:https://www.youtube.com/watch?v=756iTGMrkcs |

The video (linked below) states that the three channels are isolated (as fyl2022 mentions) and the spec sheet has "series and parallel configuration data, but you are right that this is not specifically mentioned. I had this question too. Video in Amazon listing: I also found this video which seems to be made from Matrix that talks about a similar model. It doesn't seem very well edited as the guy repeats himself a lot (as if he was doing several takes and they forgot to edit out the ones they didn't want? ... lol), but it does help fill in some gaps.
