  • Great little power supply for the price
Size: 32V 6A
OK I have to admit that I bought this power supply for exactly one reason: It's short. Every other hobby-class power supply I could find was tall (>6") and narrow. I had a space on my workbench that required one that was short and wide ("landscape" instead of "portrait"). I had recently bought the Matrix MPS-3010D+ linear power supply and been impressed with the quality, so I figured maybe this one would be good too. That said, I'm quite pleased with it. I currently have six bench power supplies (both linear and switching) in the house, and this is not the best, but it's also not the worst. And given the size and price it's a great deal. I originally thought I would hate that you can't just change the voltage or current without pressing a button, but actually I love that feature. It means I don't have to worry about bumping a knob and frying my circuit. Likewise, other reviewers have complained that when you press the V/I button, it doesn't remember which digit you were previously using, but I've come to think that's a good thing too for the same reason. It always starts with the least significant digit, so there's no danger of dialing in a high voltage or current by accident. - When you first power on the unit, the output is turned off, which is good for safety. The ON/OFF button toggles the output. - It remembers the last V/C setting you used. - There are 5 memories that are easy to use. Just long-press a button to store the V/C setting or short-press to retrieve it. - Long-press the OVP/OCP button to set over-voltage limit. Long-press again to set the over-current limit. While in these modes a short-press of the button turns on or off the OVP and/or OCP feature. These are absolute values that if the PS exceeds (actual output, not set output) it will go into a fault state regardless of whether you've actually manually selected a higher V/C in the main setting. - In normal operation, the display shows actual voltage and current (in constant-current mode, the voltage will be less than the set point). - When setting the voltage/current, the output changes in real time. The current display shows the SET current, not the actual current, while changing the voltage. So be careful changing the voltage if you're worried about too much current being drawn (this is actually a great time to use the OCP mode, which shuts off the output if this happens). Now, for accuracy. All measurements were made with a Siglent SDS 1104X-E scope with the PS feeding a 50 ohm dummy load (max 0.6A @ 30V) and with a cheap multimeter (DMM). Set 0.10V = ~100 mV RMS (103.5 mV DC on my DMM), Stdev 4.8 mV, ripple < 100 mV p-p, 2 mV RMS @ ~500 Hz Set 1.00V = ~910 mV RMS (996 mV DC on my DMM), Stdev 48 mV, ripple < 100 mV p-p, 4 mV RMS @ ~1.8 kHz Set 5.00V = ~4.95V RMS (4.99 V DC on my DMM), Stdev 60 mV, ripple < 100 mV p-p, 5 mV RMS @ ~14 kHz Set 30.00V = ~30.15V RMS (29.9V DC on my DMM), Stdev 180 mV, ripple < 200 mV p-p, 5 mV RMS @ ~200 kHz So in general voltage is quite accurate, especially when measured with a DC DMM, although it seems a little worse than spec when using RMS on the AC scope (note spec is usually done at full load, which I couldn't do). Ripple is within spec and isn't bad for a switching power supply, but as other people have said it might not be the best choice for RF work. Putting my spectrum analyzer next to it I don't see any obvious emissions from 10 kHz to 1 MHz and it hasn't interfered with my ham radio 2 feet away. Unlike a lot of other PS I've tested, this one never has a voltage overshoot when you turn off the output, or when you turn off the entire PS. When you turn off the output, it takes ~100 ms for the voltage to drop from 10V to zero and 75 ms to rise from zero to 10V when you turn it back on. These delays are normal for a switching power supply. All-in-all I'm quite pleased with this PS. It has a lot of features other units in its price class are missing, and it seems to be accurate and "clean" enough for most uses. I highly recommend it. ... show more

  • Nice supply but VERY loud fan.
Size: 32V 10A
I own 5 of the 6amp variety and they are about half as loud as the 10a version. I'll be replacing the stock fan with something way quieter.

  • MPS-3206 Power Supply Meets Its Specs
Size: 32V 6A
The MPS-3206 power supply was tested and met its specifications. Additional testing showed reasonable performance for a bench power supply in this price class. While this power supply is rated at 6A, over current protection can be set as high as 7A. The voltage and current can be set precisely in 1mV and 1mA increments using the digital setting knob. A press of the knob selects the digit and rotating it moves the value up or down. Not as simple as an analog knob, but can easily get more accurate settings than an analog knob. Power Out: 15V at 6A (90 watt), ran for 1 hour with no issues 25V at 6A (150 watt), ran for 1 hour; temperature at exhaust fan air outlet 85F Meter Accuracy: Both voltage and amps were within 1% of my 1% accuracy meter Noise at 90W and 150W: 100mV p-p, main frequency of noise ~50kHz Noise with no load: 10mV p-p, main frequency of noise ~20 MHz Fan: Off at lower power, somewhat noisy when on, measured 52 dBA at 1 meter Tested it charging a LiFePO4 battery at 2A. Many of the inexpensive power supplies have difficulty regulating current, particularly near the transition between constant current and constant voltage. This power supply showed a maximum p-p variation in charge current of 15mA measured at 1 second intervals. No current variation was seen when driving a resistive load in constant current mode. ... show more

  • Nice Little Power Supply, with one problem
Size: 32V 6A
I have been using this for 3 months. It has one problem. It kills its own power switch. It seems to be a design problem. When the power switch is turned on or off, it generated spark across the contacts and melts the contact together. I have replaced the original switch with some cheap small switches. They were killed almost right-away. I'm still waiting for a replacement switch. Hopefully, they'll send a better quality switch that will not get stuck. Another small problem is the way it remembers the Volt and Current settings when you turn it off. Ideally, it should keep whatever setting it was at the time you turned it off. But it does not, it remembers only the last settings you recalled from the memory. So, say, you have a memory setting of 12V and 1A. You recalled it. After that, you changed the setting to 5V 0.1A, without saving to a memory. You turn it off and back on. The setting will be 12V and 1A. It has caused me a little problem once. I turned it off and on again without checking. For the price, this is a very good value. It's a switching power supply, so there is noise on the output. But it has the control for output on/off. It measures current down to 1ma. It also has memories to store frequently used settings. It is very small, much smaller than the normal bench top power supply. 4/22/2022, I did receiver a couple of replacement power switch. I put one in and have not had the problem since. ... show more

  • Nice build quality but be careful setting it up
Size: 32V 6A
The DC output is relatively low noise and the regulation about what you expect for a switching regulator. The UI is a little onerous and clunky to setup and use, and if you don't set up the supply correctly you can inadvertently overvoltage whatever you connect. IMO you need to setup your buttons to go in order from low voltage to high voltage. If the supplies are out of order I think it would be easy to inadvertently select a wrong voltage on powerup. The enable/disable button is a great idea, but be aware that the voltage will fall at a rate defined by the supply output capacitors and any capacitance in your project. I do wish supply providers would use a FET output switch with very low capacitance on the output terminals. Overall, it's a great little supply for the price. ... show more
