The power will be consumed by the transducer and the load RM.

What datzsheet the total power consumption of the transducer? The device itself needs 10mA continuously from both supply rails to work.

Datasheeet that this is the worst case possible, where you continuously measure 50A DC. Sign up using Facebook. It is never driven into saturation if operated within spec and never leaves zero so there are no hysteresis effects either.
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. So the maximum power drawn will consist of two components: The amplifier runs a current through the coil winding so that the flux in the core sums to zero. And next to that it will 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.

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. If you lx55p sine-shaped or small currents, I s will on average be smaller, and so the average power will drop.
This is represented in the schematic by the X-box. Marko Gulin 1 5 Worst case for the transducer will lq55p with maximum current and voltage drop into minimum RM. All of these devices work using Hall-effect sensors.
Post as a guest Name. Email Required, but never shown. This current transducer has 2 supply pins: The flux cancelling current is fed to the output and will be directly proportional to the primary current.
If I s flows out of the device it will be drawn from the positive supply and vv.
