| | Excellente alimentation !!! | 2023-06-01
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 | 2020-07-16
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 | 2020-04-29
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 | 2020-02-27
Exactly what I needed for my research.

A good hobby power supply . It has many uses.
| | Simple and Compact | 2017-10-12
Economical and well made Variable Low Voltage DC Power Supply.

ok
| | Most excellent. | 2016-04-17
Put it together, and use itThat simple.It holds values set, nice and clean DC voltage.

Had to. Send one back other is working.
| | ok for the money | 2016-02-28
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? | 2016-02-16
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. | 2016-01-25
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.

Remember to get a transformer.
| | Versital tool to any electronics tech. | 2013-12-07
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 | 2012-06-22
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 | 2011-07-05
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 | 2011-03-07
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.

What is Trustami

Trustami regularly scans the internet for new reviews and collect them in one place, in order to make them available to interested parties at a glance.

We want to make it as easy as possible for every internet user to look up products. Instead of relying on just one source, we provide a single point of contact to get easily all the reviews on a product.

Trustami does not generate new reviews and stays independent in order to make the internet more transparent. We automatically search on popular internet platforms and websites to find reviews and identify products. Our claim here is to provide a helpful set of product information that anyone can rely on. The aggregation of product data is done as good as possible and may include multiple versions of one product.

Trustami was created as a project of the Technical University of Berlin (TUB) with the aim of making the internet more trustworthy. Research in the field of "Social Media Analytics & Big Data" at the Chair of Information and Communication Management (IKM) provided a first prototype that enabled the collection of reputation data. With further development and funding Trustami became an independent spin-off.
