Hi,

Does this module support continous 15A without any cooling for hours?

It seems to me that screws and connector are not suitable for 15A on each phase.

Did any one realy tested this module for an hour with Maximum load of 15A?

Thanks,

Roee

Hi Roee,

Which module are you referring to?

Hi Roee,

The screw block terminals are rated for 16A. The traces, sense resistors, and power MOSFETs are all rated for at least 15A.

For EVMs we will do a steady state thermal test to ensure the components remain within their operating parameters.

This test is done until temperature climb effectively plateaus (would not last for an hour).

This is done under nominal free air, room temp conditions, so of course results can vary based on environment.

Nick please also update about your test results.
Will it be done soon ?
Thanks,

Hi Roee,

No further testing is planned. I was outlining what is done on our EVMs.
