wandows Posted July 28, 2022 Report Share Posted July 28, 2022 Hello everybody! I would like to count on the help of friends!!! In the offset adjustment, my power supply has the output voltage >= 32.9V, and does not reduce to 30V. Any tips on what can be done to solve this problem?

gixap92915 Posted January 7, 2023 Report Share Posted January 7, 2023 I only have unused 15V-18V-20V-24V-CT 5A transformer, how to get it working with liqubyte's 0-30V-rev-8 schematic? What parts I have to replace/add? Also does liqubyte's 0-30V-rev-8 is the last stable revision? Thanks. Quote Link to comment Share on other sites More sharing options...
a.devincentiis Posted November 8, 2023 Report Share Posted November 8, 2023 Hi everybody, I improved by digitizing this circuit and replaced the final stage with that of the equally famous K7200. You can scale it both in voltage and current by changing a few components because the three opamps are always powered at 27V Sorry, article is not complete and not yet translated into English Quote Link to comment Share on other sites More sharing options...
paul .a larner Posted April 8 Report Share Posted April 8 can someone tell me how to connect an external rectifier to this?,i have one like an alluminium block with one corner chamfered representing + out from the bridge,can anyone tell me what points to connect what place on the pcb to,a pic would be best,thanks Paul l.

It is impossible to diagnose homemade circuits at a distance as there are just to many places to go wrong. For others never build something you can buy cheaper. Get two at 8$ each - one for parts. https://www.ebay.com/itm/Stabilized-Continuous-Adjustable-DC-Regulated-Power-Supply-Kit-0-30V-2mA-3A-L/353345066780?hash=item524501d71c:g:JjsAAOSw~QteWLkt Hi am new here, i recently bought the kit, its ok to use schema and part list rev 7 for 3A with two output transistors ? I plan to use a pair of 2N3055 or there is a better choiche ? Thanks Quote Link to comment Share on other sites More sharing options...
