Bench power supplies can be basic, and they can be complex. This tutorial video covers essential, basic bench power supply tips that all electrical engineers should know. They are crucial for electronics work, lab work, electrical design work, and can blow up your devices if they aren't used properly.
This video explores 9 tips and capabilities you should look for in your bench power supply.
Load regulation - the variability in the output V/I due to change in load. Some loads will not tolerate voltage variations greater than a few percent
Line regulation - the variability in the output V/I due to change in AC input
Programming accuracy - the quality of the programmed value being near to the actual V/I
Read back accuracy - the quality of the displayed value being near to the actual V/I
Resolution - the smallest value of V/I that can be programmed
Output noise - consists of common mode and normal mode
Transient response - time taken for the output voltage to return to the programmed state after a disruptive change in load current
Sense connections - local and/or remote sense capability
Interface - front panel and/or remote (LAN, GPIB, USB, RS232, etc.)
Low noise, excellent regulation, and remote sensing capability that reduces the voltage drop across load leads, are the desired characteristics in a power supply.
When dealing with power, safety comes first. Sometimes when devices fail, it may be catastrophic. It is important that a power supply not only protect itself, but also protect the DUT. Protection circuits in the power supply can limit the voltage or current to a preset level or shut down the power supply when an overvoltage or overcurrent condition occurs. Some power supplies also have a down programmer circuit to quickly discharge the DUT while some, upon receiving a fault trigger, are able to open a relay and isolate the DUT from the source of the power.

    Nice done! You mention several important parameters, usually found in the datasheets for power supplies. One parameter that I think is harder to find is the supply’s “easy to use”. It is of course not easy to specify this and what is easy or convenient is also depending on your personal preferences. But I think there some universal features such as clear, logic and configurable display, possibility to set voltage and current both by keypad and knobs, dedicated output on/off buttons. How does Keysight work when designing UI? Can I as a user influence this? I have an E36313A and think it has really good UI, but really miss the possibility you had on e.g. the old HP66312A. With the left and right arrow keys you could move the cursor to one digit and when increase/decrease it with the up or down arrow or the knob. An easy way to step the output voltage in e.g. 0.1V steps while observing your DUT to see when it shuts down or wakes up. May we see a FW update with this feature? :)

    I wish that the E36313A had more annunciation options, such as 4 short warning beeps (similar to ST:TNG error) when transitioning from voltage to current mode that could be accompanied by fast channel button flashing on the affected channel. For an OCP trip perhaps there could be a long beep with the shutdown channel flashing slowly somehow. (breathing?)

    I am getting back into electronics as a hobby and my career. I'll be working as an instrumentation mechanic at a power plant. From the video it appears Keysight manufacturers triple benchtop power supplies, what models of power supplies do recommend for a novice like myself? I also just purchased "The Art of Electronics" and in Appendix L they recommend the HP E3630A but I've not been able to find any place that sells these units new out of the box. Any recommendations would be appreciated. I'm looking forward to viewing more of your videos. Cheers from North Pole, Alaska!🎅🎄

    From Bill: Programming accuracy really means setting accuracy. You can set the voltage from the front panel, LAN, or USB. Program accuracy defines how closely the voltage output will be to the setting. Readback accuracy defines how accurately we measure the output voltage which is displayed on the front panel, and sent over LAN, or USB.
