Post as a guest Name. What is the total power consumption of the transducer? If I s flows out of the device it will be drawn from the positive supply and vv.

And next to that it will draw I s from the supply “in general”. Worst case for the transducer will be with maximum current and voltage drop into minimum RM.

This is represented in the schematic by the X-box. It is laa55p driven into saturation if operated within spec and never leaves zero so there are no hysteresis effects either. So the maximum power drawn will consist of two components: In that case you will need to find the rms value of the current you measure to determine the average power you will need for driving I s. You might want to re-phrase the question. This current transducer has 2 supply pins: If you measure sine-shaped or small currents, I s will on average be smaller, and so the average power will drop.
The amplifier runs a current through the coil winding so that the flux in the core sums to zero. This is rather clever as it removes all non-linearities of the core from the performance of the device.
Thank you for clarifications, this is really helpful! The power will be consumed by the transducer and the load RM. All of these devices work using Hall-effect sensors.
Yes, I only care about the power budget since I need to size a power supply.
I suspect you only care about your power budget in which case your analysis is correct. Note that this is the worst case possible, where you continuously measure 50A DC.
