Digitally controlled bench PSU project update

Yet another update on Bertho’s digitally controlled bench PSU project we covered previously: Did some test-bed assembling today and did a dry-test of the power board. The good news… the power board did not blow up ;-) The aux PSU for +/-12V analog and the 5V logic supply switcher is working as it should. The power […]

DIY small bench power supply

newtonn2 posted detailed instructions of how to make this DIY small bench power supply that can adjust with precision current or voltage: After making my Mini Adjustable Power Supply I was very happy with it, but I was missing a more accurate control of the voltage and current. So I decided to make this slightly […]

Digitally controlled bench PSU project update

An update on Bertho’s digitally controlled bench PSU project, we wrote about it previously: Finally some spare time to get the PCBs finished and on order. Lets see how many brainfarts are there to be discovered ;-) Expected delivery in a couple of weeks, so there is some time before I can dive into the lab to […]

Home built bench power supply

Ian Johnston wrote a post on his blog detailing his bench power supply build: My workshop has a couple of bench power supply’s, one is an old Farnell TOPS 3D 3-rail tracking job, and the other is a 3-rail CSI CSI3005XIII with Constant Current functions. The farnell is all analogue but has no constant current control, it has […]

Designing and building a bench supply

Another article that might help with bench power supply designs: A good, reliable and easy to use bench power supply unit is probably the most important and most used device in every electronic lab. A proper electronically stabilized bench power supply unit can easily cost over 200 Euro.  Using a clever microcontroller based design we […]
