I've seen many benchtop power supplies, but those USB ports are a nice, and nowadays necessary, feature.

Thanks DIYer! They're very handy for micro-controllers and charging up phones etc..

Great job knoba. This is a nice project. Planning to incorporate USB ports to my wall outlets.

Sounds great. I hope you're going to publish the build...

I've been looking for an inexpensive 24v DC power supply.
Do you know how many amps it will handle?

Thanks for posting the neat thread

in its current state, at 24V it will deliver 1 amp, which is the maximum that you can get out of the 12V- terminal. If you wanted to increase this current rating you would have to change the diodes in the -12V line to diodes which will cope with more current. If you did this, you would also need to put a heat sink on the new diodes. Here is a link to someone who did this:
