The Yokogawa CT1000 AC/DC Current Sensor enables non-invasive, high-precision current measurement across power electronics, automotive, and industrial automation applications. This clamp-on sensor delivers 1500:1 current transformation with ±(0.05% of reading + 30 µA) basic accuracy, eliminating the need to break circuits during installation. Operating from DC to 300 kHz, the CT1000 measures DC currents to 1000 A and AC peak currents to 1000 Apeak (1500 Apeak for CT1000A variant), making it suitable for demanding measurement environments where accuracy and safety are critical.
