The device itself needs 10mA continuously from both supply rails to work. Worst case for the transducer will be with maximum current and voltage drop into minimum La5p. So the maximum power drawn will consist of two components: 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: Home Questions Tags Users Unanswered. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

And next to that it will draw I s from the supply “in general”. Sign up using Email and Password.

This is represented in the schematic by the X-box.

It is never driven datashret saturation if operated within spec and never leaves zero so there are no hysteresis effects either. The amplifier runs a current through the coil winding so that the flux in the core sums to zero. Email Required, but never shown.

The datasheet is not very comprehensive so I am guessing a bit. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to dataheet policies.

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 be directly proportional to the primary current. 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.

I suspect you only care about your power budget in which case your analysis is correct.

Current consumption of a current transducer (LEM LA P) – Electrical Engineering Stack Exchange

Yes, I only care about the power budget since I need to size a power supply. Marko Gulin 1 5 You might want to re-phrase the question. This is rather clever as it removes all non-linearities of the core from the performance of the device.

Post as a guest Name. If I s flows out of the device it will be drawn from the positive supply and vv.

All of these devices work using Hall-effect sensors. What is the total power consumption of the transducer?
