I am trying to upcycle an old bit of tech I had lying about. The main part I am looking to recycle is the power supply however I do not have specs of the power supply itself. I have measured an output of about 5.5V with a multimeter but what more can be done to calculate/determine, the maximum load of this component.
Below you will see a photograph of the said PSU, the device actually has dual PSU (presumably for redundancy as the two were wired in parallel).
I have googled any distinguishing marks on the PCB with no avail: this was probably a proprietary board built for this machine.
I am hoping someone can suggest which components I should look at to determine what the maximum load is or a practical method to test.
In terms of what I would like to achieve I would like to use this to power two raspberry Pis that would fit nicely in the chassis of this device. I am fairly certain there is enough power but I would like to determine more about this PSU before hooking it up and possibly look into ways of protecting the Pis from over voltage/current.
