1. Summary

CTA series is the ultra-accuracy transducer that can measure both DC and AC. Its current range covers from 60A to 2000A with precision of 0.03% and 800 kHz bandwidth. By using Flux-gate technic, the CTA series realized high accurate measurement, excellent linearity, low DC offset, lower temperature drift, low insertion loss, high immunity to external field and low noise.

 

CTA series transducer includes CTA60(60A),CTA200(200A),CTA400(400A),CTA700(700A)  CTA1000(1000A) and CTA20002000A. CTA60 ,CTA200,CTA400 have measurement aperture of 26mm; CTA700,CTA1000 have measurement aperture of 30mm and CTA2000 have measurement aperture of 70mm. CTA series transducers have standard 9 pin D-Sub male interface and LED Indicator, making the system not only easy to use but also reliable.
