Technical Data - Camille Bauer EURAX UI 505 Mode D'emploi

The measured variable I or U AC is isolated from the elec-
tronics by the transformer W, and is rectified and smoothed
in the rectifier unit G following. The output amplifier V, re-
ceiving its power supply from the measuring input, converts
this quantity into a load-independent DC output signal.
