And next to that it daatasheet draw I s from the supply “in general”. 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 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 device itself needs 10mA continuously from both supply rails to work.

The amplifier runs datashee current through the coil winding so that the flux in the core sums to zero. The flux cancelling current is fed to the output and will be directly proportional to the primary current.

Worst case for the transducer will be with maximum current and voltage drop into minimum RM. If I s flows out of the device it will be drawn from the positive supply and vv. dahasheet
Thank you for clarifications, this is really helpful! This is rather clever as it removes all non-linearities of the core from the performance of the device. Home Questions Tags Users Unanswered. Email Required, but never shown. So the maximum power drawn will consist of two components: You might want to re-phrase the question. I suspect you only care about your power budget in which case your analysis is correct. The datasheet is not very comprehensive so I am guessing a bit. What is the total power consumption of the transducer?
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 power will be consumed by the transducer and the load RM.

Yes, I only care about the power budget since I need to size a power supply. Sign up using Email and Password.
