Yokogawa Test & Measurement Releases AC/DC Split Core Current Sensors for EVs and AI Data Centers
August 19, 2026
News
Yokogawa Test & Measurement Corporation released the CT500SA and CT200SA, its new AC/DC split core current sensors. The devices are designed for accuracy and to simplify current measurements in high current applications such as electric vehicles (xEVs) and renewable energy. Ideal for space constrained applications, the solutions deliver high-accuracy current measurements for the 200 A and 500 A ranges. The sensors are compatible with both power analyzers and waveform measurement instruments.
Highlights:
Compact measurement in tight spaces:
- 110mm width × 62mm height × 25mm depth
- Single unlock-and-open button for one-handed clamp-on installation
- M4 screw hole and cable tie slot to secure the sensor in place
High accuracy, wide bandwidth, split core design:
- Accuracy of ±0.09% of reading + 0.01% of full scale within a temperature range of 23 ± 5°C
- CT500SA delivers a frequency bandwidth of 500 kHz (−3 dB)
- CT200SA extends to 1 MHz (−3 dB)
- Measure switching frequencies
- Phase accuracy of ±0.1° (0.1Hz ≦ f ≦ 1kHz)
The CT500SA and CT200SA are engineered for EV/xEV, renewable energy (Photovoltaic (PV) / solar), HVAC, and AI data centers.
