DC Shunt Heat Dissipation..
(OP)
Anybody got a table of some sort with a general rule of thumb for heat loss on DC Shunts. The manufacturer of the ones we've ordered doesnt seem to have got that info!?!?
range 0-100A, 60mV output
cheers guys

Doesn’t 100A · 0.060V = 6W still work?

Your shunt is just a resistor, much the same as an electric fire element or a tungsten lamp. The only difference is that the resistance is very small and the volt-drop is therefore small. Ohm's Law still applies.
P = V * I
or
P = I^2 * R
Both give the same result - 6 watts.

If we learn from our mistakes,
I'm getting a great education!

just after your post i spoke to somebody who imformed me the same..

No problem, JR. The informal nature of Eng-Tips is handy for that reason.
