SNEAX 55 With power supply RMS value measurement, with measuring ranges Carrying rail housing P/0 Application he transducer SNEAX 55 (Fig. ) converts a sinusoidal or a distorted AC current into a load independent DC current or a load independent DC voltage proportional to the measured value. he transducer fulfi ls all the important requirements and regulations concerning electromagnetic compatibility EMC and Safety (EC 00 resp. EN 00). t was developed and is manufactured and tested in strict accordance with the quality assurance standard SO 00. Fig.. ransducer SNEAX 55 in housing P/0 clipped onto a top-hat rail.
