Rigol DP832 Triple Output 195 Watt Power Supply

I initially balked at the price of this thing, but I needed a new bench supply so I pulled the trigger and held my breath. I was really afraid this was going to be some Chinese junk with pretty paint and a bunch of issues. Nope! Its a very well-designed piece of equipment. In fact, you’ll pry this out of my cold, deads hands. I LOVE this power supply.Its a linear supply. Its heavy. Feels very solid in the build quality. No rattles, missing screws, or fit/finish issues at all. But the proof is in the juice. The output is very tightly regulated and shows a ripple of (get this) 0.00011 volts. 110 microvolts. This while powering a 1 amp resistive load at 5 volts.There are upgrades for this machine. Google it for specs, but in short this supply can be enabled to track down to .001 increments in both volts and amps. Darned impressive.Its rare that I fall in love with something from China, but this box really has me grinning. Its worth the price and more. It is very well-behaved and makes for a smooth experience on the test bench. If you are looking for a decent value with upgrade potential, look no further than this unit.

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.

Great machine yet not all features are enabled which is a bummer. Its like buying something from motorola. It contains all the hardware for the features but requires a license key to activate Ethernet etc.. Otherwise its a good all around power supply.

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!

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.

Awesome piece of tech, the available functions at this price point are pretty amazing. Seems very well made, I'll be putting it through its paces so we'll see how it holds up. I suspect it will do great on my bench. I like the overvolt protection, and while some people dig the rotary phone style pad (not sure what they were thinking) - you do get used to it, and it's a non issue.New programmable power supply.....CheckTake over the world....in progress

Turns on, but no display. Tried many times, Buttons light up, but are unresponsive. Display remains dark.Quite a bummer........

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
