Siglent Technologies SPD3303X-E Triple Output Power Supply

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. ;)

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.

It isn't cheap but I am very pleased with this unit. Very intuitive interface and very easy to use. Power outputs can be connected together to get a negative voltage reference. (As in +32 to -32) Note that earlier reviews mentioned how the banana binder posts don't properly hold a standard banana plug and the connections are very loose - to the point of falling out. Siglent evidently fixed this issue - mine fit perfectly and the connections are tight. It would be nice to have the higher resolution unit (1/1000 instead of 1/100) but I could not justify the substantial cost increase for my needs as a hobbyist. I would buy this unit again. Update: I have had this unit for 9 months and no issues. However, if I was buying it again, I would spend the extra money to get the SPD3303X for the higher resolution. Oh, I have read other reviews on Siglent equipment that the unit was believed to be out of cal when received. I thought the same thing because it is not obvious when the calibration was performed at the factory unless you look closely on the correct side of the calibration sheet. The calibration is good for one year AFTER YOU turn the unit on for the first time.

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.

Alimentatore molto buono, per quello che devo fare direi oltre aspettative
