Review: Love it! A must have for the serious hobbyist (and even the not so serious) :) - After watching many reviews on this power supply, I decided to buy it. It was a good choice for the price range. Its performance is spot on, although on some voltage ranges, you MIGHT notice a .01 volts difference on the screen from what you choose and what the output actually is. It's not a big deal and since there are only 2 digits past the decimal point, that .01 may actually be something like .006. If that's a big deal, then dial in the voltage you want, minis -.01. So for 12.00 volts, choose 11.99 volts. But that is so not a problem. As expected, it's a bit heavy, but that's due to the transformer inside, which are always heavy. I actually like the heaviness and it gives it a feel of good quality, which it is. LOVE IT! UPDATE: OCT 2019 STILL LOVE IT! Use it daily. :) UPDATE: JUN 2020 YUP! STILL LOVE IT. Still used daily. ;)
Review: Très bien pour un amateur averti - Les photos parlent d'elles même. La seule remarque que je peux faire, c'est que le canal 2 est plus près de la tension voulue.

## Questions & Answers

**Q: Will this power the flux capacitor?**
A: Unfortunately, not nearly enough power. At 300W, we would need 4 million SPD3303X-Es to reach the 1.2 GW needed to power the original flux capacitor as well as 4 million power cords, 4 million outlets, etc.. it would be a bit of a challenge :)

- Jason, SIGLENT NA

**Q: does it have a current limiting feature?**
A: Yes, the two main outputs each have a programmable current limit with the same fine granularity as voltage setting. The third 3.3/5V output I think is a fixed limit.

**Q: How does it behave when powered up from the ac input?  does it begin working with last settings, or must the soft power button be pressed to start?**
A: This has a hard power switch, you can tell by looking at the power button the line in the middle does not touch the circle. when you power it up, your last settings used will still be there but it will not be enabled. Hope this helps.

**Q: Can you adjust the tree outputs?**
A: I assume you meant three instead of tree. However, channel 1 & 2 (0-32 volts)are adjustable. The three outputs of 2.5, 3.3, and 5 volts @ 3.2 amps are fixed and selectable by a slide switch. A comprehensive user manual is available for this power supply that details all the features. Very happy with mine!

*by C***N on 25 July 2024*

Les photos parlent d'elles même. La seule remarque que je peux faire, c'est que le canal 2 est plus près de la tension voulue.

### ⭐⭐⭐⭐⭐ Buena fuente de poder
*by F***Z on 11 May 2022*

Buscaba una fuente de poder para mis proyectos de electrónica (no soy profesional) y cumplió su objetivo. Ya venía con el firmware mas reciente y el selector de voltaje/fusible configurados para mi país. Me gusta que tiene un puerto ethernet y se puede controlar remotamente. Así pude generar gráficas en la computadora.
