    Multi input AC Voltage measurement?

    Are you aware of devices or devices I can configure as shown notionally in the attached drawing?

    Needing to measure 220VAC 3ph on 15 different inputs and select input and report voltage RMS via Ethernet or USB to the test controller.

    Any hints appreciated.

    thank you

      Do a search on "branch circuit monitoring" and see if that gives you something you can use.

          Texas Instruments bq24745 bq24745RHDR bq24745RHDT Battery Charger IC for Laptop Computers Datasheet
          by Document Archive
          The bq24745 bq24745RHDR bq24745RHDT is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5-mm x 5 mm QFN package.

          The bq24745 features dynamic power management...

          Modifying SMPS input voltage range
          by Dannyx
          Good day folks. Long time no see. It's been a while since I've tinkered with any new projects, despite one thinking this would be the perfect time, with the pandemic and the quarantine, people tend to stay indoors....it's not my case anyway: I go to work like normal, but it's here where I'm bored out of my mind with nothing to do, so here's something.

          A while back, I got myself this adjustable load kit form off Ali. I put it together and it works. It's powered by an AC or DC input and I've been running it off a 12v wall adapter on the bench. What good is such a device if it doesn't...

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...
