Able to turn on each channel individually.
Like everything about.

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 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.

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.
