## Description

MATRIX 30V 10A Variable DC Power Supply - Linear Bench Power Supply for Electronics Testing & Laboratory, MPS-3010D+: desertcart.com: Industrial & Scientific

Review: Nice Linear Power supply - This power supply functions very well, and is reasonably priced for a linear supply. Build quality seems good. Two factors to consider: 1. It is much heavier (~17 lbs) than a switching supply - so if you are going to move it around a lot - just be aware. 2. There are reports (I did not measure this) that there can be transient voltage spikes when using the "Output" switch. If you are using very sensitive components you may want to physically disconnect power leads before turning on the output. This does not effect what I use it for. There are "workarounds" posted on the internet to address this - adding capacitance stage to output etc. Overall It works well for me.
Review: Mostly Works - Update Jan 22, 2021: I was contacted by Matrix and asked to evaluate another unit and update my review. I received the new power supply today. It did not work. It powers on and the displays react to turning the knobs. When I press the Output button the Voltage drops to half of the set value and the amperage goes to 0. I opened it up and found a loose connector to the interface board that was supposed to be glued into place had worked loose. It still did not work until I found the 220VAC/110VAC switch was set to 220VAC. When I set it correctly it started operating. I could not get it to output 10A it kept shutting off output when it got above 9.57A at 14.6V. It would shut off at 8A at 5.7V. It did operate from 5.6-30.0V as indicated, but not near 10A. It still doesn't work as well as the first one. It still goes into "OTP" and shuts off at 14.7V 9.0A and just shuts off output at 14.7V 8.5A. So still not working as described. Kudos for trying Matrix, but still a failure. Original Jan 2021: I bought this to charge LiFePO4 batteries and cells at 10A. I took a chance based on the one review. It mostly works. The output function where the current and voltage can be set ahead is a very nice feature (also why I took a chance on it). I charged my EcoFlow Delta 1400 at 30V set at 9.99A for over 8 hours. The EcoFlow settled at about 8A 240W charging rate. Changing the voltage on power supply didn't change the charge rate. The EcoFlow Delta is rated at 400W charging. The MPS-3010D+ power supply was hot to the touch when charging stopped and it heated the room substantially. I went to charge my 24V 50Ahr LiFePO4 battery with it at 9.99A and 29.2V. First when I depressed the "Output" button nothing would happen. There are 2 distinct clicks when it engages the load. I then disconnected the battery then activated the output and started charging the battery when I connected it. Within a few minutes it shut off (the relays make very distinctive clicks) and "otp" showed in the Volt display. It was not hot that I could feel, but I did not open it up to find out. I tried this 3 more times and it does the same after a few minutes each time. The included manual which has a different model number than what I received is silent on the "otp" display. I contacted desertcart Product support which was no help. She recommended I message the Seller (that system is even worse) after she attempted to contact the seller via phone. I received a response from the seller after about 12 hours. Seller was attentive (3 responses) and suggested adding a diode to prevent reverse polarity from the battery, and using it at 8.0A instead of 10A. I then tested it at 8.0A, 8.5A, 9.0A, and 9.5A at 29.2V all at CC. The "otp" kicked in at all above 8.5A. Not acceptable to list at 10A and it be usable at 85% rating. Typical Chinese crap rate it too high then they say "we really didn't mean that" rhetoric. It is going back. The manuals clearly states that using it near its limits will shorten its life. If its usable limit is 85% listed then it will have a very short life. I have a 35 year old HP linear power supply (0-50V, 500mA) that still works. Overall, if you need a 30V 8.5A power supply instead of a 10A power supply this may work for you. I do not recommend it. I have no patience with products rated over usable specifications.

### ⭐⭐⭐⭐ Stable power supply
*by J***K on April 1, 2022*

Using it to power a 12V - 10 Amp heater. The voltage and current settings drifted 0.03 V and 0.05 amps as it warmed up and has been stable ever since. The only additional info I have is that the supply boots up in the standby - voltage / current setting mode, you have to press the Output button every time to get voltage output. This is not a problem for a bench supply, but could be a problem in a test setup that's automated.
