RUZIZAO DC Power Supply Variable, 30V 10A Adjustable Regulated Bench Power Supply Lab Switching Power Supply 3-Digits LED Display 5V/2A USB Port(Black)

I was a bit dubious about buying a power supply without a known name but it works well, exactly as described, very easy to use and give an accurate voltage readout. Small and lightweight which is ideal for my cramped little work space.

It seems to work well. I use it mostly to charge lithium batteries. I set the voltage at 14.6v and the current at 8 amps. The power supply shows constant current for a few hours. Then, for the last 30 mins (approx), it switches automatically to constant voltage until the current reduces to almost zero and the battery is fully charged.

When using be careful to observe what mode it is in, either constant voltage or constant current. Instructions with it are not to clear.But device is very useful when circuit requires limited current or voltage.

My son bought this for various hobby projects. Got the 30v 10amp version which has plenty of power for what he needs.If you short it out, it limits the output to 10amps so does not blow a fuse or burn out like an older style power supply would.The variable voltage and variable current is great. I borrow it to run my mini Dremel-like drill.

I tend to not write reviews unless there is something wrong with the item, but this product is performing better than expected. The Voltage and Amperage accuracy is excellent for the price. There is a small voltage drop when you connect a load to it, but they warned about it in the product description and to be honest its so small that it make very little difference. I do not think you can get a better DC Power Supply for this price.

Worked perfectly

Once unboxed I wasn’t sure it would be up to a load of more than a couple of amps as there is no weight to this PSU at all.Plugged in and connected to my digital load bank and happy running at a couple of amps and only a couple hundred milliamperes divination between display and load voltages.Ok happy at an average load I’d be using so all in I’ll bring it up to full voltage and amperage.Happy running 32 volts at 10 amps for roughly 10 minutes and fan was happily running and no real deviation or AC noise on the supply.Overall really really happy with these little supply and despite its lack of weight it packs the punch it says it can.I’ve since bought two more and they preform the same.All in all a good variable voltage PSU that does what it says it can.

very light and portable, the readout was spot-on with accuracy, and i got an extra discount so i got real value for money

utilissimo per un banco prove

Bonjour. Le produit a était livré avec un câble alimentation (comme pour un PC) mais on ne peut pas le branché sur une prise standard (2p+t ). En effet la connectique pour la terre est boucher par du plastique. Il paraît impossible à retirer sans abimer la prise. je me sers d'une autre prise récupérer pour l’alimenter. Il y a une légère rayure sur le devant. Comme annoncé dans un précédent commentaire la fiche technique est en allemand. Très léger ce produit est vraiment le standard de l'alimentation de laboratoire DC. Il vas me servir a vérifier la fonctionnalité de petit appareil électrique.

Marche très bien 'et facile a faire

Excellent rapport qualité prix

Buona l'estetica e la robustezza. La misura del voltaggio è precisa. Inconvenienti: non c'è una regolazione della protezione in corrente sulla manopola, quindi sai quanto il carico consuma ma se vuoi inserire un blocco a (es.) 2A non lo puoi fare prima. O meglio... basta attaccare una resistenza, aggiustare la tensione in fino ad avere 2A, e poi girare la manopola della corrente fino a quando cade l'alimentazione. Come hanno detto altri, sarebbe stato meglio avere un interruttore per spegnere l'uscita senza spegnere tutto l'alimentatore. In cavo in dotazione è Shuko, ma la presa è standard schurter e un cavo si trova sempre
