| | Excellente alimentation !!! | 01/06/2023
Bonne alimentation simple tension positive réglable. Prévoir un radiateur pour le LM317 pour une différence de tension entre VIN et VOUT importante, dépend aussi du courant en sortie.
| | A very useful circuit | 16/07/2020
A very useful circuit intended to provide a stabilised voltage supply when used with a low voltage transformer. Can also be used to provide a stable lower voltage, e.g. a reverse voltage protected 5 volts from a 12 volt supply, for small currents. (Note that it is linear so it will get hot and will need a heatsink for currents approaching 1A).
| | Good value for money | 29/04/2020
I am very pleased with this kit. I was easy to construct and set up. It also performs well for my purpose as a power supply for a small audio amplifier.
| | Excellent | 27/02/2020
Exactly what I needed for my research.

awesome
| | Five Stars | 03/05/2018
A good hobby power supply . It has many uses.
| | Simple and Compact | 12/10/2017
Economical and well made Variable Low Voltage DC Power Supply.
| | Four Stars | 08/09/2016
ok
| | Most excellent. | 17/04/2016
Put it together, and use itThat simple.It holds values set, nice and clean DC voltage.
| | Four Stars | 27/03/2016
Had to. Send one back other is working.
| | ok for the money | 28/02/2016
I bought two of these, they went together fine. My only complaint is with the voltage adjustment pot. There is no way to finely tune the voltage, way too sensitive.
| | Used components? | 16/02/2016
Kit arrived clearly in damaged packaging. Didn't think anything of the legs on the LM317T until it was time to solder that component on. Moved forward and assembled the kit but when I got to the point of the LM317T, found that the LM317T came with the legs cut off too short to insert through and solder onto the throughhole board. Further, the truncated legs showed clear signs of plier/grasping tool damage
| | Einfach zu bauen. | 25/01/2016
Alle Erwartungen erfüllt. Macht ,was es soll.Allerdings liegt der ermittelte Eigenverbrauch bei ca.1,5 Volt von 12 Volt. Man sollte immer etwas mehr an Spannung "einfahren", damit noch genügend Reserve vorhanden ist.

does the job

Remember to get a transformer.
| | Versital tool to any electronics tech. | 07/12/2013
This power supply is great, one reviewer said "where's the transformer," well it doesn't have one, it accepts either AC or DC power up to 40 Volts and delivers clean DC power from about 1.5 v to 36V (or about 90% of what you supply it with. At work we have tons of 24VDC power supplies but when we want to bench test a load cell (15VDC) or anything not 24 volts you just put this inline adjust the pot to what voltage you want and your ready to go. If you don't have a
| | Don't see | 22/06/2012
I don't see a step down transformer, does it includes one? Don't forget that in order to get 1.5V to 35V a step down transformer is needed and then a rectifier circuit
| | Design Change | 05/07/2011
I had to return this item because there was a design change and the product no longer matches the picture. New design is nicer IMHO, but it won't fit my enclosure. See the pics on the Velleman site for the new design.
| | power supply for DTMF unit | 07/03/2011
After i puting it together,i have 12 volts for mic preamp and using that power supply i bring it down to 9v for DTMF ENCODER GENERATOR WITH PIC FROM EBAY So i have split the line (12 volts ) one for pre-amp and one for Power Supply. So the Velleman 1A 1.5V-35V Power Supply Kit work real good.

Cos'è Trustami

Trustami cerca regolarmente in Internet nuove recensioni per raggrupparle in un unico posto e renderle immediatamente disponibili agli interessati.

Vogliamo rendere il più semplice possibile per ogni utente di Internet scoprire i prodotti. Invece di fare affidamento su un'unica fonte, offriamo un unico punto di contatto per ottenere tutte le recensioni su un prodotto con poco sforzo.

Trustami non raccoglie di per sé alcuna recensione e, in qualità di autorità indipendente, si adopera per rendere Internet più trasparente. Le piattaforme Internet e i siti Web più diffusi vengono ricercati automaticamente per trovare recensioni e identificare i prodotti. Il nostro obiettivo è offrire una raccolta utile di informazioni sui prodotti su cui tutti possano fare affidamento. L'unione delle informazioni sul prodotto viene eseguita nel miglior modo possibile e può includere diverse varianti di prodotto.

Trustami è nato come progetto dell'Università tecnica di Berlino (TUB) con l'obiettivo di rendere Internet più affidabile. Il lavoro di ricerca nell'area "Social Media Analytics & Big Data" presso la Cattedra di Information and Communication Management (IKM) ha fornito un primo prototipo che ha consentito la raccolta e la raccolta di informazioni sulla reputazione. Questo è stato poi ulteriormente sviluppato come parte di una borsa di studio sponsorizzata ed è ora uno spin-off indipendente.
