I have a set of these:

Specifically M1.UM which outputs Voltage.

I am looking to use these Monday for some test measurements into a PQA however it only takes 1A or 5A Current inputs.

Are there any transducers available that will scale this for me?

I have one Rogowski coil here that will sort of let me away, but ideally I'd like 3 phase. My local supplier has no more Rogowskis' in stock right now.

Space is too limited for standard Open-coil CTs.
 
Something like this is close:

The load I'm measuring is motor FLC at 80A, but currently star-delta so a peak inrush is expected.

The PQA is a Janitza 512 Pro, and whilst I've only ever used 1A or 5A input, in the software it lets you select mA.... hmmm...
