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.

Great unit, much better than I expected. Controls take some getting use to, but once target voltage set unit works well. The ability to switch the supply on / off without killing the unit is expected but not present on some other units. Very pleased with this purchase.

Wery simple operation, precision adjustable voltage and current. Good quality for money.

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 charging Even 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 charge And 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.

Ein vorzügliches, kleines Netzteil mit immerhin 300 W Leistung. Nahezu selbsterklärend, scheinbar solide und es gibt keine Mängel. Ich habe tatsächlich Freude daran.

Mooie voeding, intuïtieve bediening.

Bonne alimentation (pour l'instant reste à voir sur la durée), très facile à utiliser, pilotable depuis le PC (pratique quand on développe des projets sur des microcontrôleurs). Le seule petit défaut que je lui trouve c'est la puissance indiquée sur le logiciel PC qui est arrondie à 2 chiffres après la virgule alors que le logiciel affiche 3 chiffres, le troisième étant toujours 0. Pour la tension et le courant on a aussi 3 chiffres après la virgule mais là ils sont tous utilisés. Je pense que ce "problème" vient du fait que c'est l'alim qui fourni cette donnée et que sur l'écran de cette dernière on n'a que 2 chiffres après la virgules pour la puissance et donc le logiciel ne doit probablment recevoir que 2 chiffres après la virgule. Sur la photo on a un exemple, 4.498 volts et 0.204 ampères, ça devrait normalement faire 0.918 watt or le programme affiche 0.920.

Belle appareil et précision

Buon prodotto complessivamente.
