Rigol DP832 Triple Output 195 Watt Power Supply

Very good, especially considering the price point. What matters to me: - Has both OVP and OCP. Quite a few more expensive power supplies have no OCP. - Good UI. The default view shows everything you normally care about. This is much better than 7-segments. I switched UI color to white for more contrast. - Good accuracy. I measured it with my Fluke 87V both un-loaded and loaded (although my DUT consumed only <0.5A total). You probably don't need that much voltage accuracy (current is another thing though) but it doesn't hurt to have it. - Ramp up seems smooth (again according to my Fluke 87V). I should have measured it with my new scope (also Rigol) though. Catches: - I know some people are bothered by the unconventional numpad layout (old-styled pulse-train telephone anyone?) but I find it okay. - Ch2 and Ch3 share the same negative terminal potential. Ch3 is intended to be a digital supply anyway (5V max) so it doesn't bother me as much.

Great features and easy to use. I read the reviews before hand, so I'm not too surprised. It did not disappoint. SOOO nice to be able to set current limit and see instantaneous voltage and current readings on all 3 channels simultaneously. Unit is very heavy, so think about this as you plan where you will place it on your bench or a shelf. The printed documentation is rather poor, so if you really want to learn how to use all the features of this power supply, you'll need to go online and watch some videos. Great set of features at this price!

Ever wonder why it's cheaper than sellers outside? Old stock from years ago. The one I ordered was calibrated a year ago and was manufactured way earlier than that. Other than that, you can trust Rigol. Regarding the power supply itself, the display was a bit too small, but everything seemed money oriented. there are many features 'locked' in the power supply. You can 'unlock' them by purchasing keys, which effectively makes it DP832A, the more expensive variant.

Love this power supply, I've been using it daily for about 9 months and haven't had any issues. The triple output has been super helpful to allow me to have multiple different test setups at once without constantly reconfiguring a single supply for each project. The user interface and configurability are all pretty intuitive and easy to use. So nice having over current and over voltage protection on each channel. This version is definitely better than the DP832A interface because it has the three channels represented vertically rather than in that stupid circular version. I have used the remote control via ethernet and it was pretty easy to use and seemed reliable. My only minor complaint is the way the number pad is circular around the dial. Would much prefer a standard numpad, but it isn't a deal breaker.

This is a very flexible power supply and has a decent UI. The rotary keypad is odd, as others have commented and I'm not sure why Rigol chose this since there other stuff has a normal layout. You might see some complaints on places like the EEVblog about overheating but in my unit (made July 6, 2015, this is not a problem. This unit also has firmware 1.14 which corrects some other issues you might read about. Why not 5 stars? Simple, this supply arrived with channel 1 significantly out of calibration. That is the voltage you set using the keypad was neither the voltage you got or the voltage you read on the display. There are calibration procedures available in a manual you can download from Rigol NA's website. Have a 5 1/2 digit DMM available and be prepared to spend some time with the 40 point procedure. Now the instrument is correct for all three channels +/- about 15 mV. If you do this, the password for the manual calibration is "2012" It was odd that only channel 1 was off. Another issue that most likely will not bother most users is the presence of a 12-14 Vrms AC voltage between each of the output terminals and chassis ground. Most of the time you would not care since you would want the DC output to float with regard to ground (be isolated) but this is still odd. See the attached scope output

So far, I love it. Very easy to use.

When you want a bench power supply that has plenty of juice to go with some nice bells & whistles, this Rigol gets the job done! Perfect for driving electronics projects, small DC hobby (NiCd, NiMH, LiPO, LiFePO4) battery pack chargers, or testing components or suspect electronics. Plenty of features right out of the box with several more that can be licensed / unlocked. This is way better for the hobbyist & enthusiast than the cheap switching supplies out there, and more informative than an ATX bench mod. It hits in all the right places. Need more? Check the EEVBlog over on YouTube.

So far I have loved this power supply. It is cheap for the what it does and for the market... But only 4 stars because what is not cheap is the software upgrades. North 100USD each. I bought the high resolution, and I think I will buy all of them... but still I think they are a bit overpriced.

Très bonne alimentation de laboratoire programmable. Une puissance confortable sans être exceptionnelle et une précision au rendez-vous. De très utiles fonctionnalités. L’electronique et la mécanique sont celles de la version 832A, beaucoup plus chère. Cette référence est upgradable directement sur le site de Rigol (options payantes). Un peu bruyant (ventilateur puissant) même au repos. Un remplacement du ventilateur par un ventilateur de PC haut de gamme peut la rendre totalement silencieuse. A faire une fois la période de garantie passée. Les défauts des premières versions sont un vieux souvenir et cette alimentation est un très bon produit pour les hobbistes comme pour les pros.

Very powerfull power station, with tons of functionalities

best psu I ever owned

very good

Funktioniert sehr gut, nicht das erste und sicher nicht das letzte Gerät von Rigol.
