Luke writes, “A few years back I made a compact bench PSU based on a DPS-3002 module and a 24v PSU. I have since made a improved version that also includes the ability to run on my power tool batteries making it ultra-portable.” See the full post on his blog here.

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 […]
Digitally controlled bench PSU
Bertho posted a digitally controlled PSU design in the forum. He writes: The design is for 0…30V and 0…3A (90W) controllable at ~1mV and ~0.1mA steps. The actual accuracy is still out for testing and I assume that noise and non-linearity will be a factor to look at when time comes. The basic design allows for 0…42V […]
Bench top power supply
@mattbrailsford tweeted his DIY bench power supply. You can get one for $14 at Seeed Studio.
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 […]
