Model：CTA60 Country of Origin：China
Category：Fluxgate current transformer
Current measurement range ±60A
Accuracy up to 0.03%
The CTA series is an ultra-high-precision current transformer capable of measuring both DC and AC simultaneously. The current range is from 60A to 1000A; the accuracy is as high as 0.03%; and the bandwidth reaches up to 800kHz. Using fluxgate technology to achieve high-precision measurement, it features excellent linearity, extremely low DC offset, low temperature drift, low insertion loss, strong anti-interference performance, and low noise, making it very suitable for high-precision and high-stability current measurement. It is widely used in industrial, medical, laboratory, and other applications.
The CTA series current transformers include CTA60 (60A), CTA200 (200A), CTA700 (700A), and CTA1000 (1000A). The measurement aperture of CTA60 and CTA200 is 26mm; the measurement aperture of CTA700 and CTA1000 is 30mm. Standard 9-pin D-Sub male interface; operating status LED indication function; easy to use, safe and reliable.
