RUZIZAO DC Power Variable Supply 30V 10A High Precision 4-Digital Display Adjustable Regulated Switching DC Lab Bench Power Supply

Great price for a super product.Goes up to 60 volts which is brilliant for gold plating and anodising.

Arrived today and straight out of the box to check our accruate it is, given some reviews seemed to indcate it wasnt, well no problems with mine.Accruacy is within 0.1V or A on each range which is plenty good enough for my use.If there was one thing I'd like to improve is the "fine" adjustment, while it is "fine" I'd like it to be finer as its sometimes tricky to set it when dealing with two decimal places as it can end up jumping about but its only a minor niggle.So far very happy with the PSU.Would I recomend it....yes

I use this almost daily for testing motors. Charging low voltage batteries. Only down side is it doesn't stay on constant current mode when charging higher voltage batteries. Like our old 18v nimh drill battery. But happily charges smaller voltage ones. Has a good bonus of having a fast charge 2amp output USB which I use to charge my phone up daily and other 5v devices

Easy to use

Excellent product to demonstrate classroom electrical demonstrations.

bought for my dad to use to power his model train rolling road, and test the minic motorway cars h likes to rebuild.it's nice that this has 3 displays so you don't have to convert to watts in your head.Has been working fine for the couple of years it's been in use

Second time I turned this on it made a pretty loud popping sound accompanied by a nice flash from the inside.It continued to work but I decided that I don't need the heartache of an unreliable power supply in my life.Keeping the magic smoke inside my sensors and micro-controllers is hard enough as it is.

Great bit of kit. Easy to adjust and accurate. Must-have for any microcontroller, electronics or solar projects. I use this PSU almost daily. The pots provide good voltage/current control and I've yet to hear the fan come on despite driving up to 10A.

ottimo, economico, fa il suo dover permettendo di alimentare facilmente qualsiasi apparecchio (fino a 30 Volts, ovviamente). Comodi i connettori a coccodrillo inclusi nella confezione

Très bien plus qu'à essayer

Apres avoir signalé panne de cet équipement par email il m'a été remplacé gratuitement dans un délai très court dans le cadre de la garantie légal 1 an . Donc SAV extraordinaire - Merci

A prescindere che non sono un tecnico e non lo utilizzo per lavoro, ho acquistato l' alimentatore perché le recensioni a livello hobbystico sono soddisfacenti. Devo solo alimentare dei miei strumenti per la nautica e funzionano fra i 12v e 24v quindi con una tolleranza notevole. Per prova ho impostato l' alimentatore su 12v testato con due multimetri originali cinesi e su uno misura in uscita 12,6v mentre l' altro segna 11,97v. Non è precisissimo e sono certo che anche i due multimetri non lo sono, però per l' utilizzo che ne faccio io va benissimo e strutturalmente è anche robusto e bello a vedersi.......anche pratico.

Je l'utilise pour faire de la galvanoplastie et j'en suis très content
