By the way there exist power supplies that look just like the voltcraft 4005, they share the performance characteristics. These are worth tracking too I think. Here are some examples of these lookalikes:<br />GW Instek PSP405 (GoodWill Instek; Taiwanese) <br />DF1797B-4005 (also called: DF1797B) (Ningbo Zhonge Dftek Electronics; Chinese) <br />McVoice SNNT4005<br />Velleman PSS4005<br />Promax FA405<br />Thanks and all the best, Gerard.Anonymoushttps://www.blogger.com/profile/00163787857924605574noreply@blogger.comtag:blogger.com,1999:blog-6412238293976072298.post-8751304074793815822018-01-14T21:13:44.098+02:002018-01-14T21:13:44.098+02:00Unfortunately, these kinds of displays are usually...Unfortunately, these kinds of displays are usually made for to order. So, as I see it, there's 2 possibilities for when it fails: 1. You get another PSU and change you display with that one. 2. You replace the whole logic board with something like an Arduino or an ESP board or an ARM board and fit it with the LCD of your choosing.Electronics Playgroundhttps://www.blogger.com/profile/08696824794345680025noreply@blogger.comtag:blogger.com,1999:blog-6412238293976072298.post-7618662378944322942018-01-14T21:08:04.960+02:002018-01-14T21:08:04.960+02:00Razvan thanks for the help, good to know it can be...Razvan thanks for the help, good to know it can be done via the interface. Will proceed that way then. By the way my LCD display shows signs of bleeding (as if an inkblot is leaking behind the glass panel) I can still read the displayed values okay. But just in case, for when the bleeding would worsen and hinder reading the display - would you know an address where one can access a spare display? thanks for your help. regards, Gerard Anonymoushttps://www.blogger.com/profile/00163787857924605574noreply@blogger.comtag:blogger.com,1999:blog-6412238293976072298.post-75523877880768639892018-01-14T12:51:01.222+02:002018-01-14T12:51:01.222+02:00Yes, you can most definitely control it.

You can feed it commnads through it. here's a document detailing more of how it's done: http://www2.produktinfo.conrad.com/datenblaetter/500000-524999/510890-an-01-en-Schnittstellenbeschreibung_DPS_4005.pdf<br /><br />You can make a script (batch file script, Python, whatever flavor programming language you know) that sends certaind RS-2323 commands at certain times<br /><br />On mine, as I have replaced most of the logic board with the Rduino, do not have this feature....yet.Electronics Playgroundhttps://www.blogger.com/profile/08696824794345680025noreply@blogger.comtag:blogger.com,1999:blog-6412238293976072298.post-24119416417335639132018-01-14T00:43:31.362+02:002018-01-14T00:43:31.362+02:00Hello Razvan, can I ask you a question about the p...Hello Razvan, can I ask you a question about the power supply Voltcraft 4005? I happen to have the same model (4005) in my homelab. If possible I'd like to use the supply for driving an anodization process. For this goal I will need a supply that I can program. I must be able to program the voltage and the time. Can the Voltcraft 4005 do this do you think? -For example: the power supply must deliver 5 Volts during 10 minutes (interval A); 40 Volts for 3 minutes (interval B); 5V for 10 min (interval A); 40V for 3 min (interval B).... and so on. I need to program that sequence of intervals ABABAB. (Choose voltage value, and time value, of the interval A, and the interval B.) However I have never tried programming the 4005. Can it do that do you think? Can the supply deliver the sequence of intervals? would be grateful for your comment. Hope to hear from you later. Thanks in advance for the answer.
