Převodníky v technologii ETA

In 2001, LAS series transducers based on the new Eta technology were introduced into production.
This technology uses the integrated ASIC control element and combines the advantages of transducers with open feedback loop (O / L), i.e. low power consumption from auxiliary sources (20mAsk) and a wide frequency band (0 ... 100kHz) which is the privilege of the transducers with closed feedback loop (C / L).

Transmitters in the Eta technology are made for a rated current of 50A and 100A, they are characterized by an attractive price, compact construction, high resistance to EMC interference, good insulation and unidirectional + 5V supply voltage.
