Hochgenaue HIOKI Durchsteckwandler
High-Accuracy AC/DC Current Measurement up to 2000 A
HIOKI transducers are designed for precise AC and DC current measurements, especially in lab test environments. Depending on the model, they support currents from tens of amperes up to 2000 A (CT6877A), bandwidths from DC to 10 MHz, and accuracy down to ±0.025 % rdg (CT6904A). This enables reliable measurements of fast current dynamics with great repeatability.
Engineers use HIOKI pass-through sensors in power electronics applications where high current, accuracy, and low phase error are critical, such as inductor loss testing, and efficiency analysis. Typical use cases are motor-, inverter- and converter testing, EV drivetrain development, and harmonic analysis in electrical motors and power grid connections.
