LA55P Datasheet pdf – Current Transducer LA P – LEM

Marko Gulin 1 5 Thank you for clarifications, this is really helpful! So the maximum power drawn will consist of two components: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. This current transducer has 2 supply pins: Sign up using Facebook. This is represented in the schematic by the X-box. The power will be consumed by the transducer and the load RM.

If you measure sine-shaped or small currents, I s will on average be smaller, and so the average power will drop.

If I s flows out of the device it will be drawn from the positive supply and vv. I suspect you only care about your power budget in which case your analysis is correct.

The device itself needs 10mA continuously from both supply rails to work. The flux cancelling current is fed to the output and will be directly proportional to the primary current.

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

Worst case for the daatsheet 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. Note that this is the datasheeh case possible, where you continuously measure 50A DC. All of these devices work using Hall-effect sensors.

This is rather clever as it removes all non-linearities la5p the core from the performance of the device. Email Required, but never shown. It is never driven into 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. What is the total power consumption of the transducer?

And next to that it will draw I s from the supply “in general”. You might want to re-phrase the question. The datasheet is not very comprehensive so I am guessing a bit.
