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

    Thanks Ken!

    What makes those power supplies so handy is that both the 3.3v & 5v outputs are commonly used to power CMOS & TTL logic chipsets. If learning electronics on breadboards they are the bees' knees!

    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:
