I'm just a bit confused about this current transducer/sensor https://uk.rs-online.com/web/p/current-transducers/1383472/
I can't seem to figure out the reason for the reference voltage. Is the output voltage = to -2V when -250A is being pushed and = to +2V when +250A is being pushed? And is it linearly scaled? I.e would +1V mean +125A?
How exactly is the output working here?
