DESCRIPTION

The output signal can be directly used in oscilloscope, digital multimeters, power quality analyzer or data logger recording instrument. Excellent linearity, easy to use, measuring large current, three stall 6000A/3V, 600A/3V, 60A/3V or 3000A/3V, 300A/3V, 30A/3V, lower phase shift. In particular, it can be installed in tight spaces, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. Models range from 1 to 100,000Arms with an accuracy of 1% of reading. Rated EN 61010, 600V CAT IV, 1000V CAT III. This feature facilitates positioning the ct sensor around the conductor, enhances user safety, and alleviates the drooping effect associated with other flexible sensors.
