LA55P Datasheet pdf – Current Transducer LA P – LEM

Thank you for clarifications, this is really helpful! Sign up or log in Sign up using Google. The power will be consumed by the transducer and the load RM.

What is the total power consumption of the transducer? So the maximum power drawn will consist of two components: Note that this is the worst case possible, where you continuously measure 50A DC.

If you measure sine-shaped or small currents, I s will on average be smaller, and so the average power will drop. Email Required, but never shown.

If this is total consumption for both supply pinscan I except that the transducer is going to draw equally on each supply pin, i.

I suspect you only care about your power budget in which case your analysis is correct. Marko Gulin 1 5 This current transducer has 2 supply pins: This is represented in the schematic by the X-box.

It is never driven into saturation if operated within spec and never leaves zero so there are no hysteresis effects either.

You might want to re-phrase the question. Sign up using Facebook. Post as a guest Name. The datasheet is not very comprehensive so I am guessing a bit. Dataeheet I s flows out of the device it will be drawn from the positive supply and vv.

Worst case for the transducer will be with maximum current and voltage drop into minimum RM.

Yes, I only care about the power budget since I need to size a power supply. Daatasheet up using Email and Password. This is rather clever as it removes all non-linearities of the core from the performance of the device.

And next to that it will draw I s from the supply “in general”. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. 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 runs a current through the coil datasneet 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. All of these devices work using Hall-effect sensors. The device itself needs 10mA continuously from both eatasheet rails to work.
