Hioki CT6875 - AC/DC Current Sensor (500A DC-2 MHz 10m Cable)

• More enhanced environmental resistance performance than ever before with operating temperature range of -40 to 85°C
• Basic accuracy of ± 0.04% and phase ± 0.1° 
• Good frequency characteristics over wide band of DC to 2 MHz (amplitude) and DC to 1 MHz (phase)
• Ideal for advanced fields such as photovoltaics and fuel cells to evaluate the charge / discharge of batteries and secondary side of inverters
• Connect with oscilloscopes or Hioki Memory HiCorders (using SENSOR UNIT) to monitor waveforms

Hioki pass-through AC/DC current sensors are best-in-class devices for use with power analyzers, Memory HiCorders and high performance oscilloscopes. The CT6875 is a DC to 2MHz/500A sensor, ideal for testing inverter efficiency, inverter output power, reactor or transformer loss. The sensor uses flux gate detection within the zero flux method to deliver outstanding linear properties, enabling it to maintain high precision even at low current levels.

Unparalleled Technology Driving The Evolution of Current Measurement

Current sensor performance is maximized with the “Zero Flux (Fluxgate Detection)” measurement method. High frequency current is detected with windings (CT method), and direct to low frequency current is detected with fluxgates. Use of a newly developed opposed split coil* for the winding (CT) makes possible a broad measurement band, while strengthened shielding boosts anti-noise performance. *Opposed Split Coil: Coil in which divided windings are arranged opposite each other on a magnetic core to broaden the range of current detection

Broad Frequency Band

The CT6875 has a frequency band of DC to 2 MHz, placing it among the best-performing pass-through sensors rated for 500 A and making it ideal for measuring currents being switched at high frequencies by SiC/GaN elements.

Excellent noise resistance

Featuring a significantly improved common-mode rejection ratio compared to earlier models and improved noise performance across a wide frequency band
