Works great. An excellent addition to my bench. For most lower voltage/current outputs, the cooling fan is very quiet and almost inaudible. The ability to master/slave the 2 main supplies and independently turn them on and off is great. There is also an "ALL ON/OFF" switch for powering on all supplies at the same time (or for "oops" power-off moments, when you need a quick shutdown). The third fixed supply is also great when you are working with mixed analog/digital -- it gives you one more fixed regulated voltage supply at 2.5, 3.3, or 5 volts. The display is very bright and comfortable to read from a good distance on the bench, and the colors highlighting calls your attention to changing (or variable) values.
I haven't used the digital I/O capabilities but those will be handy someday.
Overall, this is a nice supply for the money.

Terrific power supply

A few comments: 1) if the product photo shows 32.000 volts, it is incorrect -- the SPD3303X-E has 10 mV accuracy, so the display only reads 32.00 volts, not 32.000. The SPD3303X is accurate to 1 mV (and its display shows 32.000 volts); 2) the banana posts are more widely spaced than with most other power supplies, so a Banana-to-BNC adapter will not fit; 3) the fan is delightfully quiet. So far I am finding this is my new favorite power supply; the display is easy to read, the controls are simple and intuitive, and it works well.
Overall a reliable power supply. Voltage and current values ...

Overall a reliable power supply. Voltage and current values are accurate. Computer control over USB port works. The recent software update shows both the setpoint and actual values, which is how it should have been designed originally. But only 4/5 stars because the update rate of the display (realtime voltage and current values) is slow, maybe once per second. So if there are any short current pulses they will not be visible on the display. The readout on the cheaper 8-segment LED models are practically instant compared to this. Additionally the software is not ideal, for instance if you reach 0 or the maximum value for either current or voltage, the whole unit freezes for a few seconds alerting you that you've exceeded allowed range - but in this time you cannot turn channels on/off or do anything else, just wait. The message also blocks your view of the voltage readouts. So this is ok for non-critical tasks, but should be improved for lab use.
Smooth and quiet.

I love this thing. I am new to learning electronics, I was looking for a good realiable power supply. I read reviews, checked my budget, these one fit right in. The screen is nice, the look is nice, the connectors could be better.
It seems to be a pretty well built power supply for DC voltage.
The screen is a nice resolution so it doesn't look "choppy" (if you will).
I have no complaints at all about this power supply.
I like how they are a newer company focusing on a high end market and yet offering high end equipment while they gain their name. So far I own 3 pcs of Siglent equip and I am proud to have those for the price you can get these at!
