OWONSPE6103 Programmable Lab Power Supply (0-60V 0-10 A), 300w Bench DC Power Supply with 2.8inch LCD Display and Output Enable/Disable Button,Single Channel Output with PC Software and USB Charging

Great little power supply. I've had it for a few months now as my secondary power supply on my workbench. It works as it should, particularly for the price. Output noise isn't spectacular, but acceptable for the price. I appreciate the comprehensive display and the output enable/disable button. Not all supplies at this price point have that. I also like the 5 memories -- very handy for common applications (+3.3v, +5v, +12v).Two minor qualms: (1) the power switch is on the back. This is very inconvenient when it sits on a shelf above my workbench. I purchased a small inline power plug switch to address this. (2) While the current protection works (decreases voltage in event current limit is exceeded), its response time is slow (hundreds of ms?). If you are working with sensitive components, don't rely on this function for over current protection. If you want to assure current is limited it is best to insert an inline current limiting resistor (of appropriate wattage) just in case. This isn't surprising given the low price. For the money, it is a great value -- and I do enjoy the combined voltage+current graph over time (though it is more of a gimmick than a useful tool since its response time is very slow).

So far so good this seemed the best deal to get 60 volts and 10 amps , runs cool didn’t get very warm running all day at full output hope to put it to good use well into the future

Buen producto

I was very pleased with the SPE3103 supply. Great for lab workbench with usable features. I was impressed so I bought a second supply.

Excellent for powering many devices when you are troubleshooting. The memory is great and the programmable parameters are excellent

Nose que paso pero después de dos semanas el voltaje que da en la salida está vien pero en el displey está 3v pordebajo y ya no me muestra el consumo y la gráfica de amperaje.

A word from professional Electrical Enginer. This is 300 watts supply means it can deliver up to 5A only at 60 volts or up to 10A at 30 volts. I will not deliver 60V at 10A which would require 600 watts output power capacity. Product is disqualified and should be taken down or product title updated.

the graphing of amperage and voltage is fantastic. This power supply works great as a benchtop power supply for testing and programming vehicle modules. It's really a useful tool and I'm so glad I got it!
