Great split rail PSU
5.0
So far, this PSU is accurate and precise. Wish that CH1 was 15V instead of 8V, but this isn't my only PSU so not a huge hang up. Love the different settings for the display and tracking channels 2 & 3 is a very convenient feature. Another cool option is the dashboard (dial) toggle. The only drawback is that I don't think you can modify the scale limits. Eg - power full scale is 50 watts which makes it impossible to read lower values (<5 watts). But I guess that is what the digital readout is for.

DP831
5.0
This was my first Rigol purchase and I love it! When compared to other brands, for the same money, this is the leader for sure! Using it about 1 year, it works great and I haven't run into any problems! So I purchased a second Rigol product DL3021A - what a great bargen!

Great Supply
4.0
I am very happy with this supply so far. It works as advertised. I really like the option for remote control and also the ability to program output waveforms. This should make lab testing much easier for me.
The only complaint I have so far is that the current limit settings are a little confusing. There are actually TWO ways that current is limited - one is through the familiar constant/max current function that is present in most power supplies. However, this supply also has a "overcurrent" protection setting which actually shuts the output off if it is tripped. It's important to keep these straight or the behavior will be confusing.

Overall Impression
5.0
I have used this power supply for more than 6 months. The positive and negative supply are very handy if you always deal with op amp stuff. For most of users, even professional users, this is more than good enough for them. Thinking about using it for many years, this price is the best I can find for power supply that have positive/negative rail supply.
