content: I wanted an economical three output power supply (+- 15V or so for analog, 5V or 3.3V for digital) with voltage and current monitors an all outputs. You would think there are a lot of those, but the three monitors turned out to be a rare feature. I didn't have much choice; I got an Atten PPS3203T and paid about 253€ + tax + shipping.There is a neat video on YouTube showing the operation, but it is Russian:?? ATTEN PPS3203T-3S.Based on the video, the build quality looks decent. I haven't open mine.Some notes by myself:- There is a fan, but it is not too loud. There is a beeper and it is way too loud. It can be turned off, but the setting is not memorized, you have to do that every time.-The operation is easy enough, and there are more features than I need.-Voltage is specified as <0.05% + 10mV. My Extech EX330 is only 0.5%, and I measured a 0.4% error. The ripple is specified as <1mVrms, and my old Agilent is far noiser. In other words, it seems to be the most accurate unit on my bench.-The outputs are switched on with a relay, and there is bounce transient, about 2.5V. After that, the voltage ramps up cleanly (about 150us/V) with just a hint of overshoot. We'll see if the transient is an issue on real designs; I can clean it up if needed but I hope I don't need to.-I placed it n the side of my scope and it makes my Agilent screen wobble a bit. I'll see if I need to rearrange the units on the shelf or live with it.Conclusion: About the cheapest unit available that fills my spec. Not without quirks, but being cheap, I expected that. Overall: works as advertised and fills the need; I'm happy with my purchase (reliability to be determined).

content: Hi, I just have a very simple supply but looking at the video I want to ask you if "serial and parallel" means you can for example get 96V in CH1 ? or you should do it externally?

content: Quote from: Erwin Ried on August 02, 2012, 10:41:11 pmYou don't get 96V as ch1 and ch2 are 32V max, ch3 is only 6V. Besides, parallel and serial concern only ch1 and ch2. The manual just says there are parallel, serial and independent mode, but does not explain what these are. I'm guessing you could get 1 x 64V in serial or 1 x 6A in parallel, but your guess is as good as mine.

content: Correct.Independent is obviously just, independent

content: Just got my Atten power supply rebadge under the Circuit Specialist for 299 dollars. So far I am please with my purchase. The front panel is not at intuitive as I would expect but I am getting used to it.
