    Do you know the efficiency vs output load for this dcdc module?

    https://www.cui.com/product/resource/pds1-m.pdf

    ..the datasheet doesnt say. It only says "up to 82%"

    Its the PDS1-S12-D15-M one


    *..................................
    Also this one doesnt say
    https://www.xppower.com/Portals/0/pdfs/SF_ISE.pdf
    do you know it?

    Also, the lack of an input capacitor at the input terminals of the ISE series seems very odd (diagram at bottom of last page).

    Re: Do you know the efficiency vs output load for this dcdc module?

    if the "typ" eff is 82% then this is probably at half to 3/4 load

    you can expect the eff to range from 0% @ no load, to ~50% at 25% load, to 82% at 50-75% load and then dropping to 75% at full load

    easy to measure if you have one ...
