OWON SPE3051 Programmable DC Power Supply, 150W 30V/5A High Precision 4 Digit Multiple Protection,2.8 inch TFT LCD Display with USB Port Support SCPI Laboratory Power Supply

Great unit - I needed something that went up to 60V and this fitted perfectly. Operation is easier than I thought it would be. I noticed with these digital rotary controls, the volts and amps settings are done digit at a time - ie you press a button to set in 0.1, 1, 10 units (there's a small cursor to show which digit you change) It's not the same as an analogue dial that you just turn from 0 to 11. What I didn't realise was that you can just keep it on the smallest setting and keep turning - i.e. you could leave it on 0.1 and it will move from 0.9 to 1.0 (not 0.0) It kind of works as you hope it would.The V+I graph is the default display which is a bit of a shame, it's generally not very useful versus large digits. However you can see everything on the decent sized screen - both the set V/I and the actual V/I - so it's much better than the cheaper 7-segment LED units. Particularly useful when you're using constant current mode and you can see the live voltage as well as your set maximum. (e.g. when charging a broken lithium battery cell)I can't think of any downside of the unit. It's true that you can't do 60V at 10A (it will be 5A max) - but the unit is clearly labelled 300W only, so it's fair that you are limited by total power (30Vx10A = 300W, 48Vx6.25A = 300W, 60Vx5A = 300W ... you get the picture)

Overall I'm very happy with the power supply. Having used 2 DIY power supplies, I built previously, I feel far more confident using the factory one. It is accurate and has all the required protections built in.My only critisism is, when changing the digit/decimal place, on either the volatage or current settings, the highlight cursor is not very visible.This would not stop me purchasing, but I am sure there is a better alternative.

Versatility of voltage, current & limit protection keeps any electrical/electronic device your investigating safe

I needed a 60V adjustable & current Adjustable PSU for finally charging 48VDC batteries of any type and work great finally tune the voltage and current for correct battery chargingEven tried on my car battery 14.12 V current limit to 3A although does work up to 10A worked great as you see the current drop as you near full chargeAnd the bonus is it’s also a multimeter so you can double check the output well with it very happy

I got this because it was listed as a 60v 10a supply.It is not!This power supply can only supply 10amps up to 30v beyond that as the voltage is increased the amps drop to 5 amps at 60 volts.So this power supply is about 30% more expensive than others listed that output 5 amps at 60 volts listed on amazon, and not much cheaper than others listed as 60v 10a. It’s also twice the price of the 60v 5a power supply I already own purchased from another e-commerce platform.So I will be returning this as it is underperforming or overpriced depending on your viewpoint. I should have had alarm bells going when I saw a mention of 300w or 10amps at 30volts.
