So the maximum power drawn will consist of two components: Email Required, but never shown.

The ddatasheet will be consumed by the transducer and the load RM. Thank you for clarifications, this is really helpful!

LA55P Datasheet pdf – Current Transducer LA P – LEM

This current transducer has 2 supply pins: What is the total power consumption of the transducer? The device itself needs 10mA continuously from both supply rails to work.

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

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. It is never driven into saturation if operated within spec and never leaves zero so there are no hysteresis effects either. This is represented in the dattasheet by the X-box.

Note that this is the worst case possible, where you continuously measure 50A DC. If this is total consumption for both supply pinscan I except that the transducer is going to draw equally on each supply pin, i.

The flux cancelling current is fed to the output and will datsheet directly proportional to the primary current. 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. Marko Gulin 1 5 Post as a guest Name.

All of these devices work using Hall-effect sensors. The datasheet is not very comprehensive so I am guessing a bit. And next to that it will draw I s from the supply “in general”.
