The Yokogawa CT200 is an AC/DC current sensor that transforms primary current into a proportional current output signal for integration with power analyzers and precision measurement instruments. Operating across DC to 500 kHz with a 1000:1 transformation ratio, it accommodates primary currents from 0 to 200 A DC and 200 A peak AC. The sensor delivers current output scaled to the primary measurement—for example, 100 mA secondary output from 100 A primary current—enabling direct connection to instruments with current input terminals.
Designed for power electronics, automotive, and industrial test environments, the CT200 prioritizes measurement accuracy and straightforward integration into existing setups. Primary conductors feed through a dedicated hole on the device, with secondary output delivered via connector to compatible measuring instruments. Current direction is marked by an arrow on the sensor body.
