A nice bench power supply with a serious design flaw.
1 out of 5 stars
A nice bench power supply with a serious design flaw.
I have just used this UTP1306S to power a digital receiver for testing at 5V (with 1A current limit) - it worked perfectly (5* for the PSU at this point).I needed to move along the bench so I unplugged the PSU and plugged into the next wall socket. When the power came back on, Smoke came out of my receiver, the voltage had jumped to 13.17V with 4.95A current limit set. It seems all it's voltage and current settings are forgotten when power is lostI have never had a PSU before that changes output voltage after power loss - I consider this to be a serious design flaw which could result in many over-voltage accidents with my circuits as they work on 3.3V or 5V and will be destroyed at 13V. Maybe I should resort to my 10 year old analogue PSU which has never failed me like this.

Trying to balance the unfortunate previous 1-star review... I had already some other UNI-T items, so no surprise this is a good device, for more details just check the you tube review, (the US chap who opens it).

4.0 out of 5 stars Not bad buy has some issues
Reviewed in the United Kingdom on 25 December 2019

1. The blue LEDs behind the 5 buttons (M1, M2, M3, OCP, OVP) are very, very dim when switched on (so dim that I didn't notice them until it got dark in the evening!) - you can only see them in a dark room.
2. There was a loose piece of wire (looked like a bit off a snipped component lead) sitting inside the coils of the current shunt on the front panel which could have been shorting out a turn of the shunt or could have fallen into one of the PCBs.
3. V\Amps LED readings are pretty accurate but I can't see how to tweak them (no trimmer pots)?
4. No mains switch on the front panel - I must reach over the top and round the back to switch power on\off.
5. If you press one of the Memory buttons whilst the output is enabled, it immediately changes the output voltage to the new value. It would be safer for it to switch off the output and allow you to enable the new setting after checking the voltage is what you want. You could accidentally press one of the Memory buttons whilst adjusting O/P or CC with disastrous results.
6. No 0V to Gnd terminal shorting link provided (would it break the bank to ship a 5 cent piece of metal?).
7. Ventilation holes - the fan pulls air in (when on) but they have put the outlet ventilation holes on both sides of the case. This means you can't put any other unit next to it (like another UNI-T power supply) or you will block the holes. Brilliant design guys! Why didn't they put the holes in the top of the case near the front and maybe with a grille to prevent metal wires, etc. falling in, like PC enclosures often have (heat rises after all you know).
7. When you press the V or CC knobs, it defaults to the least significant digit. It would be more useful if it defaulted to the 2nd-least significant digit, you don't very often need to adjust the voltage by 10mV and the current by 1mA. So the default should be to select the 100mV and 10mA digits when the button is first pressed in, because currently I have to press it two or three times to move it off the 10mV\1mA digit every single time I want to adjust the V\CC.
8. Firmware bug - set voltage to 32V (for example) using pot, now press M1 (for example) to set voltage to a different setting - say 3.3V. Now you can use that voltage for your circuit. Now switch off the mains power - the next day you come back and switch it on again. The setting is now back to 32V! If you didn't notice this and just enabled the output you could fry your circuit! Basically it only remembers the last settings if you manually changed the pots or if you long-pressed on the M1 button to re-save the setting before you switched it off.
9. When the fan comes on (supplying 1A at 30V for 5 minutes is enough to get it on) it is quite noisy. Video review says its quiet but mine sounds like a small jet engine (just not as loud). I might have to change it if it gets annoying.

It does have one major issue however...
Set O/P to 32V
Connect small load e.g. 1K or a bit less or no load
Enable output and connect scope probe
Now switch off mains 230V AC power
The output will shoot up from 32V to 40V before drifting down slowly to 0V. If you set the O/P to 26V or below then there is no surge on power off. Also, if you connect a larger load (52R or more) then there is no surge.

I was rather dismayed to read the reviews of this Uni T psu, which I rather foolishly did after ordering it. It looked like it would have to be returned. However the unit I received seems to have almost none of the problems listed below.

It shuts off the output when turned on and I measured no voltage spikes or other disturbance on power on. It still does not remember the preset but you can push it before enabling output or as I will most likely use the main adjusters that it does remember.

As far as I can tell on a fairly quick test it seems to work well.

Ich finde die Handhabung des Geräts sehr einfach. Die 3 programmierbaren Spannungen sind sehr praktisch und sehr genau einstellbar. Das Gerät ist sehr leise und das Display ist sehr gut lesbar. 32V und 6A für die kleine und leichte Bauweise sind sehr gut. Ich kann das Gerät wärmstens für Elektroniker, Elektrotechniker oder Reparaturwerkstätten und für jeden Hobbybastler oder Repair Cafes weiterempfehlen.

5.0 out of 5 stars Alimentation réglable compacte et efficace
Reviewed in France on 23 June 2021
Verified Purchase
Si la marque UNI-TREND excelle particulièrement dans le domaine des appareils de mesures, elle ne démérite pas dans la conception d'alimentations réglables de haute performance.
L'alimentation UNI-T UTP1306S est un concentré ultra-compact du savoir faire de la marque avec un poids de 1.9 Kg et un encombrement minimaliste de 80 x 150 x 230 (mm).
Elle peut fournir de 0 à 32 Volts sous 0 à 6.1 Ampères avec une régulation en ligne de 0.01 % et une régulation en charge de 0.1 % qui suffit amplement pour les expérimentations de laboratoire, la maintenance électronique, les travaux pratiques et bien d'autres activités.
Elle fonctionne dans un silence total car son ventilateur arrière ne se déclenche qu'en dernier ressort après un usage intensif.
Sur le modèle en ma possession la tension de sortie se situe dans une fourchette de 5 milliVolts maxi, contrôle effectué avec un multimètre 20000 points ayant subi une calibration, l'afficheur digital s'avère donc utile car suffisamment précis et bien pensé. Comme sur toutes les alimentations de ce calibre la protection en tension (OVP) comme la protection en courant (OCP) sont réglables avec finesse et débrayables au gré de tout un chacun.
La tension et le courant de sortie peuvent être verrouillés par appui prolongé sur l'encodeur rotatif de courant.
La tension de sortie sur les socles bananes peut être coupée depuis la face avant en dehors du bouton marche/arrêt secteur intelligemment placé à l'arrière de l'appareil. Attention toutefois il reste en général une tension résiduelle de quelques dizaines de milliVolts présente sur les socles bananes même si la sortie est désactivée.
Tension et courant peuvent être stockés dans 3 mémoires dont le bouton d'accès s'éclaire très discrètement. Chose primordiale : ces mémoires ne sont pas effacées si l'on débranche le câble secteur.
Lorsque l'appareil est mis en marche ni les mémoires, ni la tension de sortie ne sont activées. Mais la tension et le courant affichés correspondront à la dernière tension utilisée en mode manuel.
Au seul chapitre des regrets, l'éclairage interne beaucoup trop discret des boutons M1, M2, M3, OVP et OCP.
Bien entendu côté satisfactions, les performances alliées à une superbe esthétique sont indéniables. La notoriété hors pair de la marque UNI-TREND alliée à un rapport qualité-prix maitrisé font de cette alimentation réglable une référence incontestable.
Note importante : vous remarquerez peut être que la boîte contenant l'alimentation a été ouverte et refermée avec une adhésif qui n'est pas d'origine UNI-T. Cela ne signifie pas qu'elle a été utilisée mais simplement complétée par une feuille de caractéristiques en Allemand (sur le lieu probable d'importation). Le mode d'emploi est en Anglais et Chinois uniquement.

Despues de 1 año y medio,usandola puedo decir que estoy totalmente sastisfecho.

NOTA: Esta fuente memoriza la ultima tension que usaste antes de apagarla.Con respecto a esto algunos usuarios sin fijarse han conectado un circuito y al pulsar el ON de la fuente se ha quemado.Para no tener ese problema la fuente debe estar conectada a 220v pero por medio de un interruptor y al encender el interruptor en una de las fases de 220v te indicara el voltaje que quedo memorizado.con lo cual no le daras al ON de la fuente por despiste.Tan sencillo como lo que expongo.Espero que os sirva a alguno.Yo lo tengo asi y sin problema alguno.
