Show your favorite and most used benchtop PSU
Satbeginner:
My power supplies are both Chinese.
The linear 30V, 30V and 5V one has current limiting.
But I changed both voltage adjust potentiometers to proper 10-turn ones, so now at least I can get the values I want.
The single 60V one is a switch mode power supply I use to test solar, grid connected inverters. This one too has current limiting.
Un saludo,
Leo

Submitting Kikusui PMX18-2A into the mosh pit
I have tons other like Kenwood, GW-Instek etc... but none that I care to USE as of now... why drive a Lada when you have a BWM sporty :-DD
PTR_1275:
The Kikusui power supplies are nice, but it bothers me (probably more than it should) that the dart terminal is between the pos and neg terminals. This means you can't use leads like the Pomona 2bc / 2ba double banana plugs, which I have a lot of and use all the time.
Is it a linear psu, or switching?

GOPHERT CPS-3205E Power Supply:
I have attached the Calibration Procedure and Specifications for the GOPHERT CPS-3205E.
By the way I added a small piece of thin (~ 0.03" thick) dark light filter (sheet stock) material between the LED Display on the PCB and the Front Panel on my units. This is to increase the contrast between the LED segments that are ON vs those that are OFF. This greatly improves the display so that you essentially only see the LED Display's active segments. This is a modification that could/should be done in all of the GOPHERT Power Supply models. I got samples of Sunlight Filter Sheet material from a store that sells and installs this stuff on home and commercial building windows to block uV, bright sunlight, etc.
I have had my CPS-3205E for at least a year and it has been very reliable. It is a awesome Power Supply for it's capability, size, weight, accuracy, and cost (~ 75 USD eBay).
Edit: Added picture (not my unit) of CPS-3205E as supplied without the LED Display Dark Filter I added.

Hello, on my Danica TPS20 (with analog Voltage/Amp display) the 5 Volt dc is working ok :-+. The adjustable 0-10 Voltage and 0-30 Voltage both gives an pernament output of - 0,531 volts :--. Does someone has any idee what this could be. I don't have an maintenance cirquit drawing). The transformer (ac) power is ok. Thanks, regards, Henk
