ebay power supply

[Tom]

I bought one ages ago (as a result of this thread) and just plugged it in. It's been running the machine ever since.

Open circuit my supply measures 42.7V (the data sheet spec is 42.8V +/- 0.5V, so no worries).
The data sheet calls this voltage "out of regulation" (ie. there's less than 5.5V or more than 13.5V on Ucr). I haven't checked what happens when I put voltage on Ucr, because the "out of regulation" voltage is the one I want, and it seems to cope with load OK at 42.7V. The 4.3 signal diagram on the datasheet (attached) is the useful one.


On my machine Ucr (pin 28) is just floating, but I should probably tie it to ground to avoid surprises. I haven't bothered because, well, it just works.

Happy days.

Thanks for the feedback - have you measured how much the 'out of regulation' 42.7V moves when your stepper motors are going at full tilt?
