The flux cancelling current is fed to the output and will be directly proportional to the primary current.

Note that this is the worst case possible, where you continuously measure 50A DC. Worst case for the transducer will be with maximum current and voltage drop into minimum RM.

Post as a guest Name. So the maximum power drawn will consist of two components: The datasheet is not very comprehensive so I am guessing a bit.

I suspect you only datashfet about your power budget in which case your analysis is correct. Yes, I only care about the power budget since I need to size a power supply. If you measure sine-shaped or small currents, I s will on average be smaller, and so the average power will drop.

This current transducer has 2 supply pins: 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.

The amplifier datasheef a current through the coil winding so that the flux in the core sums to zero. All of these devices work using Hall-effect sensors. If this is total consumption for both supply pinscan I except that the transducer is going to draw equally on each supply pin, i.
This is rather clever as it removes all non-linearities of the core from the performance of the device. You might want to re-phrase the question. The power will be consumed by the transducer and the load RM.
What is the total power consumption of the transducer? Marko Gulin 1 5 And next to that it will draw I s from the datasjeet “in general”. The device itself needs 10mA continuously from both supply rails to work.
