The Matrix MPS-3033X is a clone of the ITECH/KEITHLEY/BK Precision triple output linear power supplies that support 30V/30V/6V at 3A per channel (it actually goes a bit higher, see image for details). So far, this device holds up to its claims and operates similarly to the brand names mentioned above.First off, the matrix MPS-3033X came well packed with a manual and cal sheet. I spot checked a few values on the cal sheet and it seems to be accurate. One of the first things I did with this unit was tear it down to do an internal inspection to verify the internals matched the listing images - it does!. My initial impression was that the boards were clean and well laid out, connectors were glued, it uses a nice toroidal transformer that was properly isolated from the chassis, the internal AC connections and grounding were clean and properly connected to the chassis, and the AC components were isolated from the DC in the same way the above brand(s) isolate. Fan noise is always a complaint with power supplies and I am pleased to say that this unit is SILENT! Even when I have it under full load, the fans kick on only as much as needed and are barely audible. The back of the unit has the terminals for sense line inputs for all channels, as well as USB and RS-232 with settings that can be changed in the menus. There is no GPIB port on the Matric MPS-3033X, which means that remote control is limited to the digital serial interfaces. The one gripe that I have (which isn’t worth taking off a star) is that the binding posts are not the standard 0.75” spacing for banana to BNC adapters (see images).This supply has a resolution of 1mV/1mA, which is usually considered a “high resolution” feature that other units in this price range don’t offer. Additionally, I could not find a three-output linear supply with sense inputs for less than the $1200 price range (being the new Rigol DP2031) Using this supply, I noticed that the measurements were accurate (verified using calibrated measuring equipment) and the software operation of the unit was nearly identical to the other brands(s). The display is larger and brighter than the equivalents, and the panel layout is the same. If you are already familiar with the above products, you will be right at home with the MPS-3033X.Over at the EEVBlog, I wrote an in-depth review with scope captures comparing the Matrix MPS-3033X with the BK Precision 9130B (its BK equivalent) to see how it stacked up to an established product. Overall, it performed quite favorably!I performed several stress and fault tests, which the unit handled and recovered from without issue. One of those tests was a 1Ω constant load test that causes other supplies (like the Rigol DP800 series) to aggressively alternate between constant voltage and constant current mode (and in some cases damaging the channel). Like the BK I had, the Matrix went into constant current mode and stayed there until the load was disabled, at which point it quickly recovered. Other features like the independent/serial/parallel/track modes also work very well.Amazon prohibits external URL’s in reviews, but my EEVBlog review can be seen in the attached (long) image. Additionally, searching for “Matrix MPS-3033X 3-channel 198W Isolated PSU - REVIEW (UPDATED WITH CONTENT!)” in the EEVBlog Forum site will bring up the thread with user feedback.The Matrix MPS-3033X is a solid unit with very competitive features at its price point! Thanks Matrix!Quick Comment: I wanted to address something that was mentioned in another review about the screen being scratched and smudged. There is a protective film that you need to remove over the clear plastic. It is there to protect the screen during shipment as the packing foam presses up against the face and the unit moves in transit. I pealed the film off and the screen is perfect.
